Temperature and surface traps influence on the THz emission from InGaAs diodes

Monte Carlo simulations forecast Gunn-like oscillations at ~0.75-1.25 THz in InGaAs planar recessed diodes (slot diodes); however, up to date no experimental evidence of this effect has been observed. The effects of temperature and surface charges on the emission parameters from InGaAs diodes are analyzed by means of an ensemble Monte Carlo simulator. Cooling the device down to 77 K strongly impro…
