Paper Abstract

Recent work on electro-luminescent cooling has focused either on diodes at forward bias voltages just below the bandgap energy, where high cooling power density is possible, or voltages below the thermal voltage, where the effect is more tolerant to parasitic non-radiative recombination. Here we consider the possibilities for diodes designed to operate at intermediate voltages. Numerical calculations suggest that design for this regime may enable near- and mid-infrared devices capable of solid-state refrigeration with sufficient power density for some applications.
