@inproceedings{4075, abstract = {{The formation of misfit dislocations is an important issue for the performance of heteroepitaxial micro- and optoelectronic devices. We analyze three approaches that quantify the stability of misfit dislocations in axial-heteroepitaxial nanowires with respect to applicability and predictions of critical nanowire dimensions. The “nanoheteroepitaxy” approach of Zubia and Hersee proves suitable for determination of strain partitioning in the presence of an elastic mismatch. Concerning the critical thickness and diameter however the descriptions of Ertekin et al. and Glas respectively yield more reliable results, owing to the consideration of the total coherent and dislocation related energies plus the residual strain energy. In contrast to the model of Ertekin et al., which refers to infinitely long nanowires, the other two mentioned approaches allow predictions of the critical thickness of mismatched deposits on the nanowire axial face.}}, author = {{Riedl, Thomas and Lindner, Jörg}}, booktitle = {{Symposium YY – Elastic Strain Engineering for Unprecedented Materials Properties }}, location = {{Boston (USA)}}, number = {{1664}}, publisher = {{MRS Online Proceedings}}, title = {{{Comparison of Theoretical Approaches Predicting the Coherent-Semicoherent Transition in Nanoscale Axial Heterostructures}}}, doi = {{10.1557/opl.2014.325 }}, year = {{2014}}, } @article{4076, abstract = {{This contribution analyzes the reliability of strain and rotation variation determination using cross‐ as well as phase‐only correlation of experimental wide‐angle electron backscatter diffraction (EBSD) patterns. For both rotation and three‐point bending the resulting displacement gradient tensor components are examined in terms of magnitude and statistical scatter as a function of various correlation procedure parameters and signal‐to‐noise ratio. It is shown that on the one hand the Fourier filter width has a major impact on the strain results. At higher noise level a smaller filter width has to be applied for obtaining maximum precision. On the other hand, the influence of the degree of overlap of the regions of interest positioned in the patterns is less important. For both rotation and bending experiments the cross‐correlation variant yields a smaller standard deviation with respect to phase‐only correlation, in particular for elevated noise level. The difference is attributed to the stronger propagation of noise effects in the course of phase‐only correlation function calculation and fitting. In the rotation experiment a standard deviation of ∼1.0 × 10^−4, averaged over the displacement gradient tensor components, and a rotational precision of ∼1.5 × 10^−4 rad have been achieved by using optimized evaluation settings. }}, author = {{Riedl, Thomas and Wendrock, H.}}, issn = {{0232-1300}}, journal = {{Crystal Research and Technology}}, number = {{4}}, pages = {{195--203}}, publisher = {{Wiley}}, title = {{{Reliability of high-resolution electron backscatter diffraction determination of strain and rotation variations using phase-only and cross correlation}}}, doi = {{10.1002/crat.201300217}}, volume = {{49}}, year = {{2014}}, } @inproceedings{4078, author = {{Riedl, Thomas and Kovács, A. and Meertens, D. and Lindner, Jörg}}, location = {{Warsaw (Poland)}}, title = {{{Structure and surface chemistry analysis of ultra-thin reactive ion etched GaAs (111) nanopillars}}}, year = {{2014}}, } @inproceedings{4079, author = {{Rüsing, M. and Merten, L. and Reinert, P. and Rogalla, D. and Becker, H.-W. and Lindner, Jörg}}, location = {{Paderborn}}, title = {{{RBS of gold-coated polystyrene nanospheres}}}, year = {{2014}}, } @inproceedings{4080, author = {{Lindner, Jörg}}, location = {{Dresden (Germany)}}, title = {{{TEM investigations on the nanoheteroepitaxy of semiconductors }}}, year = {{2014}}, } @inproceedings{4082, author = {{Lindner, Jörg}}, location = {{Porquerolles (France)}}, title = {{{Microscopic studies of plasmonic nanostructures II}}}, year = {{2014}}, } @inproceedings{4083, author = {{Lindner, Jörg}}, location = {{Jena (Germany)}}, title = {{{Nanostrukturierte Oberflächen, nicht nur zum Spass}}}, year = {{2014}}, } @article{4335, abstract = {{We explore the impact of ∼500 MHz surface acoustic waves traveling across a commensurable plasmonic grating coupler.
