The II-VI semiconductors - Characteristics and applications
Abstract
The characteristics, preparation, and applications of semiconductors combining group II and VI elements are reviewed. Characteristics which distinguish these compounds from other semiconductors include their large band gap range, the existence of a metal/semiconductor transition, their spin-orbit resonance effect, and effects related to the introduction of magnetic ions in the crystal lattice. Their miscibility and the ability to vary their band structure by anionic or cationic substitutions make these compounds particularly useful for electronic and optical applications. CdS/Cu(x)S heterojunctions have achieved photovoltaic efficiencies of up to 9 percent. Cathodoluminescent efficiencies of greater than 20 percent have been obtained using ZnS:Ag,Cl (blue) and ZnS:Cu,Cl (green) luminophores.
