ABSTRACTWe investigated the optical and electrical properties of ZnO single crystals coated with KCl by examining the photoluminescence (PL) at 9 K and the temperature dependence of the carrier concentration. The band-edge PL intensity of the KCl-coated sample was much larger than that of the uncoated sample. Moreover, a substantial increase in Hall electrons was observed in the coated sample. X-ray photoelectron spectroscopy revealed bonding between chlorine and zinc atoms in the coated sample. Therefore, coating the surface of ZnO single crystals with KCl enhances the donor concentration and improves the surface state.

The presence of CrO42− ions incorporated substitutionally in single crystals of NH4ClO4 grown from saturated solutions containing 0.1 mol% or 1 mol% CrO42− ion has been demonstrated by measurements of optical absorption, Raman scattering, dielectric loss, and ionic thermoconductivity. The three latter experiments also show the presence of dipoles associated with the CrO42− ions. The dc conductivity of NH4ClO4 crystals is enhanced by doping with CrO42− so that charge transport by defects introduced by the CrO42− ions is inferred. The implications of this finding with respect to mechanisms of charge transport in ammonium perchlorate are discussed.
