Abstract

The observation of spontaneous emission from phosphorus doped Si with a doping concentration of 0.9 X 10¹⁵ cm^-3 and 2 X 10¹⁵ cm^-3 is reported. Population inversion between the 2p₀ state and the 1s(T) and 1s(E) states was achieved by optically pumping with a CO₂ laser. The spontaneous emission increased with pump power. Electrons could be excited from the 1p₀ state into the conduction band due to the absorption of background radiation or radiation from a far-IR probe laser. The frequency dependence of the absorption is in agreement with the cross section for photon ionization of a transition from the 2p₀ state into the conduction band.
