Future Information Technologies: Germanium telluride's hidden properties at the... Germanium Telluride is an interesting candidate material for spintronic devices. At BESSY II, a Helmholtz-RSF Joint Research Group has revealed how the spin texture switches by ferroelectric polarization within individual nanodomains.
Order in the disorder: density fluctuations in amorphous silicon discovered Such a-Si:H thin films have been used for decades in solar cells, TFT displays, and detectors. The results show that three different phases form within the amorphous matrix, which influences the quality and lifetime of the semiconductor layer.
