Short wavelength infrared avalanche photodetector using Sb-based strained layer superlattice
Arash Dehzangi, Jiakai Li, Manijeh Razeghi
We demonstrate a low noise short wavelength infrared (SWIR) Sb based type II superlattice (T2SL) avalanche photodiodes (APD). The SWIR GaSb/(AlAsSb/GaSb) APD structure was designed…
