We report the first use of an electrochemical cell to dope ZnSe with potassium and the comparison of ZnSe: K with nitrogen doped ZnSe:N. At growth temperatures of 280°C potassium produces much lower doping levels but shows clear acceptor bound excitonic peaks in photoluminescence (PL), while nitrogen shows strong donor-acceptor transitions. We also report the first observation of a decrease in the nitrogen doping level in the immediate subsurface region after storing samples at room temperature. © 1993.
