Quantum dot spectrometer

Research output: Contribution to journalConference articlepeer-review


An account is given on the simulations and experiments on an electrically-tunable spectrally-sensitive photodetector based on inhomogeneous absorption in a self-assembled quantum dot array and resonant tunneling through a coupled quantum well layer. The preliminary device used in this study has been constructed based on several concepts using the InAs-GaAs-AlAs material system. The characteristically broad inhomogeneous dot luminescence is apparent in the device.
