Ge epitaxy at ultra-low growth temperatures enabled by a pristine growth environment
Christoph Wilflingseder, Johannes Aberl, Enrique Prado Navarette +11
Germanium (Ge), the next-in-line group-IV material, bears great potential to add functionality and performance to next-generation nanoelectronics and solid-state quantum transport…
A group-IV double heterostructure light emitting diode for room temperature gain in Silicon
Andreas Salomon, Johannes Aberl, Lada Vukušić +8
The lack of straightforward epitaxial integration of useful telecom lasers on silicon remains the major bottleneck for bringing optical interconnect technology down to the on-chip…
Photoluminescence enhancement by deterministically site-controlled, vertically stacked SiGe quantum dots
Jeffrey Schuster, Johannes Aberl, Lada Vukušić +5
The Si/SiGe heterosystem would be ideally suited for the realization of complementary metal-oxide-semiconductor (CMOS)-compatible integrated light sources, but the indirect band ga…
Effects of Alloying Elements on Surface Oxides of Hot-Dip Galvanized Press Hardened Steel
Wolfgang Gaderbauer, Martin Arndt, Tia Truglas +5
Effects of steel alloying elements on the formation of the surface oxide layer of hot-dip galvanized press hardened steel after austenitization annealing were examined with various…
Nanoscale Investigation of Microcracks and Grain Boundary Wetting in Press Hardened Galvanized 20MnB8 Steel
M. Arndt, P. Kürnsteiner, T. Truglas +8
Grain boundary wetting as a preliminary stage for zinc induced grain boundary weakening and embrittlement in a Zn coated press hardened 20MnB8 steel was analyzed by means of electr…
Out-of-Plane Magnetic Anisotropy in Ordered Ensembles of FeN Nanocrystals Embedded in GaN
A. Navarro-Quezada, K. Gas, T. Truglas +7
Phase-separated semiconductors containing magnetic nanostructures are relevant systems for the realization of high-density recording media. Here, the controlled strain engineering…
Suppression of axial growth by boron incorporation in GaAs nanowires grown by self-catalyzed molecular beam epitaxy
Suzanne Lancaster, Heiko Groiss, Tobias Zederbauer +5
The addition of boron to GaAs nanowires grown by self-catalyzed molecular beam epitaxy was found to have a strong effect on the nanowire morphology, with axial growth greatly reduc…
Large magnetic gap at the Dirac point in a Mn-induced BiTe heterostructure
E. D. L. Rienks, S. Wimmer, P. S. Mandal +15
Magnetically doped topological insulators enable the quantum anomalous Hall effect (QAHE) which provides quantized edge states for lossless charge transport applications. The edge…
Free-running Sn precipitates: an efficient phase separation mechanism for metastable GeSn epilayers
Heiko Groiss, Martin Glaser, Magdalena Schatzl +5
We report on the temperature stability of pseudomorphic GeSn films grown by molecular beam epitaxy on Ge(001) substrates. Both the growth temperature-dependence and the influence o…
Confining Metal-Halide Perovskites in Nanoporous Thin Films
Stepan Demchyshyn, Janina Melanie Roemer, Heiko Groiß +12
Controlling size and shape of semiconducting nanocrystals advances nanoelectronics and photonics. Quantum confined, inexpensive, solution derived metal halide perovskites offer nar…
Efficient room-temperature light-emitters based on partly amorphised Ge quantum dots in crystalline Si
M. Grydlik, F. Hackl, H. Groiss +6
Semiconductor light emitters compatible with standard Si integration technology (SIT) are of particular interest for overcoming limitations in the operating speed of microelectroni…
Centrosymmetric PbTe/CdTe quantum dots coherently embedded by epitaxial precipitation
W. Heiss, H. Groiss, E. Kaufmann +7
A concept for the fabrication of highly symmetric quantum dots that are coherently embedded in a single crystalline matrix is demonstrated. In this approach, the formation of the q…
