Abstract
We present a detailed investigation of light emission phenomena connec ted with the presence of hot carriers in AlGaAs/GaAs heterojunction bi polar transistors. Electrons heated by the strong electric field at th e base-collector junction lead to both impact ionization and light emi ssion. A new general-purpose weighted Monte Carlo procedure has been d eveloped to study such effects. The measured hot electroluminescence i s attributed to radiative recombinations within the valence and the co nduction bands. Good agreement is found between theory and experiment.
