Ge${}_{136}$ type-II clathrate as precursor for the synthesis of metastable germanium polymorphs: a computational study

Daniele Selli, Igor A. Baburin, Roman Martoňák +1

The response to compression of the clathrate type-II structure Ge(cF136) is investigated by means of \textit{ab initio} small-cell metadynamics at different temperatures and pressu…
