Multiscale hybrid simulation of brittle fracture
… atomistic model that captures the long-range elastic relaxation. The ‘Learn on The Fly’ technique is used to couple the quantum and classical models, allowing accurate quantum forces to be combined with classical forces using a simple adjustable potential to give stable dynamics. The …

Plastic Relaxation of Highly Tensile Strained (100) Ge/InGaAs Heterostructures
… previous studies have investigated the plastic relaxation occurring in these and#949t-Ge layers. Here, we experimentally demonstrate that plastic relaxation occurs in nearly all and#949t-Ge epitaxial layers that are of practical interest for optoelectronic applications, even when layers may …

Active filaments and hydrodynamic interactions in microscale propulsion
… which leads to repeated cycles of bending and elastic relaxation, and to net locomotion. Small devices designed for biomimetic locomotion need to exploit flows that are not symmetric in time (non-reciprocal) to escape the constraints of the scallop theorem and undergo net motion. Unlike other …

Germanium on silicon heteroepitaxy for high efficiency photovoltaic devices
… cyclic annealing. Because film facets allow for elastic relaxation of the applied thermal strain, the process of selective growth must be reversed: blanket Ge is to be grown instead to avoid faceting, followed by sidewall etching and filling before the cyclic anneal. Thermal expansion mismatch …
