✦ Synopsis

Thermodynamic analyses for the system ZnS:Ag (crystal)-S 2 (vapor) is performed. It turned out that it is impossible to receive hole conductivity in this system. In our experiment ZnS crystals covered by silver layer are silver doped by the mechanism of atom recoil during S + ion implantation. The resistivity of obtained p-type layers is 10 2 -10 3 W cm. The activation energy of acceptor is determined to be 0.3 eV. In the PL spectra of p-type samples l = 454 and 520 nm bands are observed and identified.
