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…
