Abstract
A layer of thickness x.sub.j is formed at the surface of a wafer of p-type ZnTe semiconductor material and compensated so as to provide insulation with high resistivity. Ions are implanted with sufficient energy to form a trapping region of thickness x.sub.1 at the surface of the semiconductor and to form beneath the trapping region an insulating region of thickness x.sub.3, with x.sub.1 <x.sub.j. The diode has high efficiency both for emission of light having well-defined wavelengths and for current generation when subjected to light radiation.
