Correlation of vertical transport and infrared absorption in GaAs/AlGaAs superlattices

Helm, M.; Strasser, G.

We have studied the interminiband absorption and the current-voltage characteristics on the same GaAs/AlGaAs superlattices. The Esaki-Tsu type negative differential resistance is observed as well as the thermal (de)population of the minibands. The possibility of mapping the nonequilibrium electron distribution function through infrared absorption measurements under bias is discussed.

Keywords: GaAs; superlattice; infrared absorption; intersubband transition; vertical transport
