Black germanium photodetector exceeds external quantum efficiency of 160%
In this work, a viable method is demonstrated to realize high-performance germanium (Ge) photodetectors (PDs) on the nanostructured Ge surface, namely black Ge, formed by chlorine (Cl2) gas-based reactive ion etching at room temperature. Black Ge surface has spike-like pyramidal structures with a wi...
