High-temperature electron-hole liquid in layered gallium sulfide
Abstract
At a temperature T = 5 K and at excitation power densities greater than or about 0.2 MW/sq cm, the luminescence spectrum of GaS contains an emission line which is due to radiative recombination of e-h pairs into an electron-hole liquid. The critical temperature of the liquid in GaS is estimated to be about 130 K, the equilibrium density about 2.3 x 10 to the 20th/cu cm, and the binding energy of the liquid about 117 meV.
