Germanium-based nanostructures have attracted increasing attention due to favourable
electrical and optical properties, which are tunable on the nanoscale. High densities of …

Combination of porosity and hydrostaticity during compression is used with a view to explore
the energy landscape of germanium. In this work, pressure-induced phase transformations …

Multi-junction solar cell efficiencies far exceed those attainable with silicon photovoltaics;
however, the high cost of materials remains a barrier to their widespread use. Substantial …
