Hidden properties of nanoscale germanium telluride
Germanium telluride (GeTe) is a ferroelectric Rashba semiconductor with many interesting properties. The crystals are made of nanodomains whose ferroelectric polarization can be changed by an applied electric field. This ferroelectric property can also be used to change the spin of electrons in each domain, thanks to the so-called Rashba effect. Germanium telluride is therefore an interesting material for use in spintronic devices, allowing data processing with significantly less energy input. Now, HZB and a team from Lomonosov Moscow State [...]
