These structures, which are known as semiconductor ... Today heterostructures composed of silicon and silicon germanium, or gallium arsenide and aluminium gallium arsenide, are used in low-noise ...

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...

A technique that deposits silicon (Si) on top of silicon germanium (SiGe) for making transistors on a chip. In so doing, the silicon atoms are stretched ("strained") to line up with the silicon ...

The group found that phosphorus doping modified the electronic structure of the silicon, while improving its power factor and carrier scattering. Germanium doping helped further improve both the ...

It represents a transformative development, potentially filling the "final gap" in the silicon photonics ecosystem. We have been exploring the fascinating possibilities of germanium-tin (GeSn ...
