@article{4229, abstract = {{The precipitation process of silicon carbide in heavily carbon doped silicon is not yet fully understood. High resolution transmission electron microscopy observations suggest that in a first step carbon atoms form C Si dumbbells on regular Si lattice sites which agglomerate into large clusters. In a second step, when the cluster size reaches a radius of a fewnm, the high interfacial energy due to the SiC/Si lattice misfit of almost 20% is overcome and the precipitation occurs. By simulation, details of the precipitation process can be obtained on the atomic level. A recently proposed parametrization of a Tersoff-like bond order potential is used to model the system appropriately. Preliminary results gained by molecular dynamics simulations using this potential are presented.}}, author = {{Zirkelbach, F. and Lindner, Jörg and Nordlund, K. and Stritzker, B.}}, issn = {{0921-5107}}, journal = {{Materials Science and Engineering: B}}, pages = {{149--152}}, publisher = {{Elsevier BV}}, title = {{{Molecular dynamics simulation of defect formation and precipitation in heavily carbon doped silicon}}}, doi = {{10.1016/j.mseb.2008.10.010}}, volume = {{159-160}}, year = {{2008}}, } @article{4256, abstract = {{We present phase-resolved pulse propagation measurements that allow us to fully describe the transition between several light–matter interaction regimes.

Laterally coupled quantum dot structures doped with two electrons are considered. We take into account interaction with acoustic phonon modes via deformation potential and piezoelectric coupling. We show that piezoelectric mechanism for the considered system is of great importance and for some ranges of quantum dot molecule parameters is the dominant contribution to relaxation. It is shown that the phonon-assisted tunneling is much faster (down to ∼ 6 ps even at zero temperature) in comparison with other decoherence processes. The influence of Coulomb interaction is discussed and its consequences are indicated. We calculate the relaxation rates for GaAs quantum dot molecules and study the dependence on quantum dot size, distance and offset between the constituent quantum dots. In addition the temperature dependence of the tunneling rates is analyzed.}}, author = {{Grodecka, Anna and Machnikowski, Paweł and Förstner, Jens}}, issn = {{1610-1634}}, journal = {{physica status solidi (c)}}, keywords = {{tet_topic_qd}}, number = {{2}}, pages = {{474--478}}, publisher = {{Wiley}}, title = {{{Theoretical study of phononassisted singlet-singlet relaxation in two-electron semiconductor quantum dot molecules}}}, doi = {{10.1002/pssc.200880319}}, volume = {{6}}, year = {{2008}}, } @inbook{5061, author = {{Backhaus, Klaus and Becker, Jörg and Beverungen, Daniel and Knackstedt, Ralf and Weddeling, Matthias}}, booktitle = {{Technologie und Dienstleistung: Innovationen in Forschung, Wissenschaft und Unternehmen Beiträge der 7.
