Abstract
Photoluminescence excitation spectroscopy (PLE) of nitrogen doped ZnSe epilayers is reported here for the first time. The dependence of the PLE spectra on the net acceptor concentration in ZnSe:N and the temperature has been investigated. A new radiative transition at 2.732 eV is revealed in highly doped ZnSe:N, and is attributed to a transition between the valence band and a new donor level with an ionisation energy of 88 meV. The effect of strain on the exciton spectra in undoped and N-doped layers is discussed.
