Zinc selenide (ZnSe) has been investigated for variety of applications including an excellent laser host material for MWIR and LWIR wavelength applications. A large number of papers have been published to grow single crystals and to evaluate suitability of ZnS and ZnSe doped with rare earth and transition metal. These ions have been used as activators in the bulk matrix for lazing. There is a continuous effort to grow better crystals and study effects of vapor transport and fluid flow. Since dopant, ions have different sizes and oxidation states. Because of this reason, point and line defects may be generated which ultimately affect the electrical and optical characteristics. In addition, these ions significantly affect point and line defects during growth by physical vapor transport. We have observed that doping with ions affects the dielectric properties and morphologies, which ultimately affect the performance of doped ZnSe.
