Direct-gap optical gain of Ge on Si at room temperature

Lasers on Si are crucial components of monolithic electronic–photonic integration. Recently our theoretical analysis has shown that Ge, a pseudodirect bandgap material compatible with Si complementary metal oxide semiconductor technology, can be band engineered by tensile strain and n-type doping to...
