Quantum dots that store large tensile strains represent an emerging research area. We combine experiments and computational modeling to investigate the self-assembly of Ge and GaAs tensile-strained...

As high-entropy alloying provides an increasingly important avenue for widening the set of functional materials for a variety of applications, it is useful to uncover synthesis routes that do not rely on large temperatures for achieving entropic stab

We introduce an approach for simulating epitaxial growth by use of an island dynamics model on a forest of quadtree grids, and in a parallel environment. To this end, we use a parallel framework introduced in the context of the level-set method. This

We study analytically and numerically aspects of the dynamics of slope selection for one-dimensional models describing the motion of line defects, steps, in homoepitaxial crystal growth. The kinetic processes include diffusion of adsorbed atoms (adat

The effects of several adatom dopants (H, Be, C, N, Si, and Zn) on the electronic structure of low-energy surface reconstructions of InAs---(001, 110, 111, and 112) low-index planes---were investigated using ab initio density functional theory calcul

In order to address an important problem in Computational Materials Design, we have demonstrated the feasibility of an algorithm which rapidly scans through various surface configurations of two single crystals selected from a crystal structures data

State-of-the-art semiconductor nanopillars are an exciting new topic, due to their unique properties that can be used in a number of microelectronic applications. Nanopillars can be grown into microarrays that can maximize surface to volume ratio, id

Using in situ electron microscopy based uniaxial compression and density functional theory calculations, we investigated the room-temperature mechanical responses of sub-micron-scale cylindrical TaC(100) and TaC(011) pillars. The TaC(100) and TaC(011

Using in situ electron microscopy-based nanomechanical testing, we show that sub-micron-scale ZrC(100) and ZrC(111) single crystals exhibit size- and orientation-dependent room-temperature plasticity under compression. We identify {} and {0 0 1} as t
