The Superior Responsivity Enhancement of Thin-Film Ge Photodetectors by AuNP Coatings
We have tried to improve the responsivity of germanium-based thin-film photodetectors. It has been shown that applying a mechanical strain to the detector led to a 46.6% enhancement on the 1550 nm detection. This improvement is better than the 1310 nm case, because the bandgap shrinkage is more bene...
