Thermionic emission in heterostructures is investigated for integrated cooling of high power electronic and optoelectronic devices. This evaporative cooling is achieved by selective emission of hot electrons over a barrier layer from the cathode to the anode. As the energy distribution of emitted electrons is almost exclusively on one side of Fermi energy, upon the current flow, strong carrier-canier and carrier-lattice scatterings tend to restore the quasi equilibrium Fermi distribution in thedoi:10.1109/ict.1997.667610 fatcat:fdszlrtpszg67pi5ew43tsi4ju
