Figure 3: Effect of temperature on experimental PETE quantum efficiency.
From: Photon-enhanced thermionic emission from heterostructures with low interface recombination
(a) As temperature increases (blue to dark red), experimental PETE quantum efficiency increases by an order of magnitude. (b) Experimental quantum efficiency as a function of temperature for photon energies between 1.45 and 1.60 eV, as marked in a. Theoretical temperature dependences for three barrier heights 0.20, 0.22 and 0.24 eV are shown in black as solid, dotted and dashed lines. (c) Internal PETE quantum efficiency at the absorber/emitter interface extrapolated to higher temperature.
