Titel:
Nonequilibrium phonon generation in coupled Wannier-Stark ladders from a semiconductor superlattice in a three-terminal device 
Abstract:
We present an experimental and a theoretical study on the midinfrared electroluminescence associated with transitions between electric-field-induced conduction states, forming Wannier-Stark (WS) ladders, in a strongly coupled GaAs∕AlAs superlattice inserted in a heterostructure bipolar transistorlike device. Electroluminescence shows wide tunability (100–210meV) of the diagonal intra-WS radiative transition, up to the merging with the vertical inter-WS emission, at constant injected emitter cur...    »
