Influence of Electric and Magnetic Fields on Interband Luminescence in Semiconductor Quantum Wires

Resumo

Interband optical transitions in quantum wires have been theoretically investigated in the model of parabolic potential in electric and magnetic fields directed perpendicular to the nanowire axis. The frequency dependences of the luminescence intensity have been calculated considering the interaction of carriers with a rough surface and with long-wave acoustic oscillations. The graphs of the frequency dependence of the luminescence intensity at different values of electric and magnetic fields, the dependences of the luminescence half-width on the wire radius have been obtained. A comparison with the experiment has also been made.
