Abstract
In this paper we demonstrate the straight correlation between the inte grated light emitted and the DC currents in GaAs-based pseudomorphic H EMTs biased at high drain voltage, when, due to hot electrons, impact ionization takes place. By means of electrical and optical measurement s, we found three different recombination mechanisms, which originate the light emission in three different energy ranges.
