Thermoelectrically Pumped Light-Emitting Diodes Operating above Unity Efficiency
A heated semiconductor light-emitting diode at low forward bias voltage V<kBT/q is shown to use electrical work to pump heat from the lattice to the photon field. Here the rates of both radiative and nonradiative recombination have contributions at linear order in V. As a result the device’s wall...
