--- _id: '4142' abstract: - lang: eng text: This paper reports the successful reduction of tensile strain in a thin ion-beam-synthesized 3C-SiC(111) layer on silicon. Significant relaxation is achieved by creating a near-interface defect structure containing nanometric voids and dislocation loops by the implantation of He ions and subsequent thermal annealing. The structural features of this defect microstructure are investigated by transmission electron microscopy. High-resolution X-ray diffraction in a parallel beam configuration is used to quantify the strain state of the top SiC layer. Further annealing experiments were carried out in order to emulate typical process conditions for the growth of wide-bandgap semiconductors like, for example GaN. It is found that prolonged annealing at elevated temperatures leads to coarsening of the voids and to a much less efficient strain reduction. We show that this issue can be resolved by the co-implantation of oxygen to form highly thermally stable cavity/extended defect structures. The technique presented here may be useful for a variety of other thermally mismatched bulk/thin film couples as well. article_type: original author: - first_name: Maik full_name: Häberlen, Maik last_name: Häberlen - first_name: Brian full_name: Murphy, Brian last_name: Murphy - first_name: Bernd full_name: Stritzker, Bernd last_name: Stritzker - first_name: Jörg full_name: Lindner, Jörg id: '20797' last_name: Lindner citation: ama: Häberlen M, Murphy B, Stritzker B, Lindner J.

The calculations aim at a comprehensive,microscopic understanding of the\r\nprecipitation mechanism in the context of controversial discussions in the literature. For the quantum-mechanical\r\ntreatment, basic processes assumed in the precipitation process are calculated in feasible systems of small\r\nsize. The migration mechanism of a carbon \x02100\x03 interstitial and silicon \x0211 0\x03 self-interstitial in otherwise\r\ndefect-free silicon are investigated using density functional theory calculations. The influence of a nearby\r\nvacancy, another carbon interstitial and a substitutional defect as well as a silicon self-interstitial has been\r\ninvestigated systematically. Interactions of various combinations of defects have been characterized including a\r\ncouple of selected migration pathways within these configurations. Most of the investigated pairs of defects tend\r\nto agglomerate allowing for a reduction in strain. The formation of structures involving strong carbon–carbon\r\nbonds turns out to be very unlikely. In contrast, substitutional carbon occurs in all probability. A long range\r\ncapture radius has been observed for pairs of interstitial carbon as well as interstitial carbon and vacancies. A\r\nrather small capture radius is predicted for substitutional carbon and silicon self-interstitials. Initial assumptions\r\nregarding the precipitation mechanism of silicon carbide in bulk silicon are established and conformability to\r\nexperimental findings is discussed. Furthermore, results of the accurate first-principles calculations on defects\r\nand carbon diffusion in silicon are compared to results of classical potential simulations revealing significant\r\nlimitations of the latter method. An approach to work around this problem is proposed. Finally, results of the\r\nclassical potential molecular dynamics simulations of large systems are examined, which reinforce previous\r\nassumptions and give further insight into basic processes involved in the silicon carbide transition." article_number: '064126' article_type: original author: - first_name: F. full_name: Zirkelbach, F. last_name: Zirkelbach - first_name: B. full_name: Stritzker, B. last_name: Stritzker - first_name: K. full_name: Nordlund, K. last_name: Nordlund - first_name: Jörg full_name: Lindner, Jörg id: '20797' last_name: Lindner - first_name: W.

These substrates are of interest for the epitaxial growth of III–V compound semiconductor stacks on their top for the production of multi-junction solar cells and very thin electronic devices. We demonstrate transfer of porous layers after an annealing process in hydrogen atmosphere. Electron Back-Scatter Diffraction analysis confirms that the substrate orientation is conserved during the etching and annealing steps. Confocal μ-Raman spectroscopy analysis shows a decrease in the Raman signal intensity after etching and a subsequent increase after annealing while no shift is observed. By means of Atomic Force Microscopy, analysis the surface appearance after the etching and annealing steps can be visualized. The mean surface roughness varies during the process from 0.55 nm for the unprocessed wafers to 0.27 nm after etching and 0.78 nm after annealing. The decrease of average roughness after etching is caused by an electropolishing step prior to porous formation. Despite of slight increase of mean surface roughness after annealing the samples are still appropriate for high quality epitaxial growth and subsequent lift-off. article_type: original author: - first_name: E. full_name: Garralaga Rojas, E. last_name: Garralaga Rojas - first_name: B. full_name: Terheiden, B. last_name: Terheiden - first_name: H. full_name: Plagwitz, H. last_name: Plagwitz - first_name: J. full_name: Hensen, J. last_name: Hensen - first_name: V. full_name: Wiedemeier, V. last_name: Wiedemeier - first_name: Gerhard full_name: Berth, Gerhard id: '53' last_name: Berth - first_name: Artur full_name: Zrenner, Artur id: '606' last_name: Zrenner orcid: 0000-0002-5190-0944 - first_name: R. full_name: Brendel, R. last_name: Brendel citation: ama: Garralaga Rojas E, Terheiden B, Plagwitz H, et al.

Überwachung von Finanzinstitutionen nicht ausreichend ist. Sowohl in den USA als auch in der Europäischen Union wird deshalb intensiv über ein neues System zur Regulierung von Finanzinstituten nachgedacht. Es ist zwar offen-sichtlich, dass eine wesentliche Ursache der Finanzkrise in den USA die Ermunterung der Finanzinstitute durch den Staat zur Vergabe von Immobilienkrediten an nicht ausreichend solvente Konsumenten war. Die vorhandenen Regulierungsinstrumente konnten die Krise jedoch nicht verhindern bzw. ausreichen abmildern. Das vorliegende Papier setzt sich zum Ziel, die Vorschläge zur Reform der Bankenregulierung zu evaluieren und insbesondere auf ihre potenziellen Wirkungen im Hinblick auf den Wettbewerb im Bankensektor zu überprüfen.\r\n\r\nIm Zuge der Diskussion über mögliche Lösungen existieren verschiedenste Vorschläge, die von Änderungen in Rechnungslegungsvorschriften über die Neuordnung der nationalen bzw. internationalen Finanzaufsicht bis hin zu einer stärkeren Berücksichtigung systemischer Risiken gehen. Die Auswirkungen der Finanzkrise haben gezeigt, dass die Abkehr von herkömmlichen Rechnungslegungssystemen hin zu Regeln der internationalen Rechnungslegung unter dem Schlagwort „Fair Value Accounting“ durchaus Gefahren in sich bergen kann. Die Debatte dreht sich insbesondere um die Frage, ob die neuen Rechnungslegungsvorschriften maßgeblich dazu beitragen, das regulatorische Eigenkapital einer Bank in Boomphasen zu erhöhen und in konjunkturellen Schwächephasen dagegen zu senken. In der Literatur ist in Hinblick auf diese Frage bislang keine einhellige Auffassung zu identifizieren. Pellens et al. (2009) gelangen zu dem Ergebnis, dass bankenaufsichtsrechtliche Normen an das IFRS-Zahlenwerk gebunden sind und dies für regulatorische Entscheidungen als besonders kritisch zu sehen ist. Durch das Konzept des Fair-Value-Accounting wurde das regulatorische Eigenkapital im Zeitraum von 2003 bis 2007 systematisch erhöht, woraus ein gestiegener Kreditvergabespielraum resultierte. Demgegenüber kommen Laux und Leuz (2009) im Rahmen einer empirischen Studie anhand von Mikrodaten aus den USA zu dem Ergebnis, dass Fair-Value-Accounting nur zum geringen Teil zu den Problemen der US Banken beigetragen hat und es im Rahmen ihrer Studie keine Evidenz für wesentliche Effekte dieses Rechnungslegungsverfahrens auf die massiven Abschreibungen der US Banken gibt.\r\n\r\nBeide Studien betonen aber auch, dass weitere empirische Forschung notwendig ist, bevor diese Frage abschließend geklärt werden kann. Die Frage des adäquaten Rechnungslegungssystems zeigt, wie vielfältig die Ursachen der gegenwärtigen Finanzkrise sind und wie schwer tatsächliche kausale Effekte zu identifizieren sind. Im folgenden Abschnitt werden zunächst die ordnungspolitischen Rahmenbedingungen einer angemessenen Bankenregulierung dargestellt. Der dritte Abschnitt umfasst einen kurzen Überblick über den Verlauf der Finanzkrise. In Abschnitt 4 diskutieren wir die wesentlichen Vorschläge zur Optimierung der Regulierung von Finanzinstituten. Abschnitt 5 evaluiert diese Vorschläge auch aus einer wettbewerbsökonomischen Perspektive. Diese Perspektive ist aus unserer Sicht vor allen Dingen notwendig, weil eine großer Teil der Reformdebatte aus Sicht der Finanzmarktstabilität geführt wird und infolgedessen Wettbewerbseffekte vernachlässigt werden. Das Fazit in Abschnitt 6 fasst unsere Ergebnisse zusammen und gibt einen Ausblick auf weiteren Forschungsbedarf aus Sicht der Wettbewerbsökonomie." author: - first_name: Justus full_name: Haucap, Justus last_name: Haucap - first_name: Ulrich full_name: Heimeshoff, Ulrich last_name: Heimeshoff - first_name: André full_name: Uhde, André id: '36049' last_name: Uhde orcid: https://orcid.org/0000-0002-8058-8857 citation: ama: 'Haucap J, Heimeshoff U, Uhde A.
