Hot Charge-Carrier Electroluminescence from Laser Nanostructures in the Spontaneous and Stimulated Emission Modes and Absorption of IR Radiation by Hot Electrons in Quantum Wells

摘要

Charge-carrier heating and the carrier concentration dependence on electric current in quantumwell laser heterostructures have been studied under conditions of spontaneous and stimulated emission. Intersubband absorption in tunnel-coupled quantum wells has been investigated under charge-carrier heating by a lateral electric field and under high-power optical excitation.
