Abstract

The observation of persistent photoconductivity in nitrogen-doped p-ZnMgSSe at low temperature is reported. The increase of conductivity after illumination appears due to a metastable population of holes which are in thermodynamic equilibrium with hydrogenic acceptors having reduced activation energy. The experimental evidence suggests the presence of a DX-like [D (donor) X center] behavior for holes.
