Microstructure manipulation by laser-surface remelting of a full-Heusler compound to enhance thermoelectric properties
Leonie Gomell, Tobias Haeger, Moritz Roscher +5
There is an increasing reckoning that the thermoelectric performance of a material is dependent on its microstructure. However, the microstructure-properties relationship often rem…
Nonlinear refraction in CHNHPbBr single crystals
Christian Kriso, Markus Stein, Tobias Haeger +5
Hybrid lead halide perovskites, such as CHNHPbX (X=I, Br), are direct gap semiconductors that offer many superior optoelectronic properties combined with extremely simp…
Applicability of molecular statics simulation to partial dislocations in GaAs
Thomas Riedl, Jörg K. N. Lindner
The suitability of molecular statics (MS) simulations to model the structure of 90° glide set partial dislocation cores in GaAs is analyzed. In the MS simulations the atomic positi…
InAs Heteroepitaxy on Nanopillar-Patterned GaAs (111)A
V. S. Kunnathully, T. Riedl, A. Trapp +3
Heteroepitaxy on nanopatterned substrates is a means of defect reduction at semiconductor heterointerfaces by exploiting substrate compliance and enhanced elastic lattice relaxatio…
Strain-driven InAs island growth on top of GaAs(111) nanopillars
T. Riedl, V. S. Kunnathully, A. Trapp +3
We analyze the shape and position of heteroepitaxial InAs islands on the top face of cylindrical GaAs(111)A nanopillars experimentally and theoretically. Catalyst-free molecular be…
Stark Effect of Hybrid Charge Transfer States at Planar ZnO/Organic Interfaces
Ulrich Hörmann, Stefan Zeiske, Fortunato Piersimoni +6
We investigate the bias-dependence of the hybrid charge transfer state emission at planar heterojunctions between the metal oxide acceptor ZnO and three donor molecules. The electr…
