Abstract
Magnetotransport and electroluminescence measurements are reported for a p-i-n AlAs/GaAs double-barrier resonant tunnelling structure incorp orating superlattices in the emitter and collector. When a magnetic fi eld of 15 T is applied parallel to the current a pronounced region of negative differential resistance (NDR) is observed. Associated with th e NDR region in the current voltage characteristic the energy of the e lectroluminescence peak from the centre quantum well is shifted by mor e than 10 meV for a change in applied bias of only 1 mV as the device is swept through resonance.
