Temperature dependence of exciton Auger decay process in Cuprous Oxide
  We report theoretical and experimental study on Auger decay of excitons in Cuprous Oxide in a wide range of temperatures, from 2 Kelvin to 325 Kelvin, in single-photon surface excitation. We find that the Auger constant linearly increases with temperature above 100 Kelvin. This constant is important for experiments on Bose condensation of excitons.
