Pulse low-energy electron beam pumped IR-lasers based on InGaAs/AlGaAs/GaAs nanoheterostructures

Abstract

Temperature dependence of threshold current density in the range 50-300 K for lasers based on InGaAs/AlGaAs/GaAs quantum-dimensional heterostructures under electron beam pumping with electron energy in the range 2-11 keV is investigated. Minimal threshold current density value as low as 0.05 A/cm2 at the electron energy of 9-11 keV and temperature 200 K is… (More)
