OSA Direct bandgap germanium on silicon inferred from 5

We report uniaxial tensile strains up to % along 〈100〉 in suspended germanium Ge wires on a silicon substrate measured using Raman spectroscopy This strain is sufficient to make Ge a direct bandgap semiconductor Theoretical calculations show that a significant fraction of electrons remain in the indirect conduction valley despite the direct bandgap due to the much larger density of
