发明名称 TUNABLE HOT-CARRIER PHOTODETECTOR
摘要 Various examples are provided for hot carrier spectral photodetectors that can be tuned. In one example, among others, a hot-carrier photodetector includes a graded barrier; an absorber disposed on the graded barrier; and a second barrier disposed on the absorber. For example, the absorber can include p-type doped GaAs. The graded barrier is disposed between the absorber and an injector, which can include p-type doped GaAs. In some implementations, the hot-carrier detector can include multiple barriers and absorbers. The hot-carrier photodetector can include an optical source (e.g., a LED) to trigger the VLWIR response in the photodetector.
