Nitrogen and helium mixed gas plasma was used to grow p-ZnSe. Using the mixed gas, the acceptor concentration can be controlled from 6 x 1016to 7 x 1017cm-3while films doped using the nitrogen plasma exhibited the acceptor concentration of 3 x 1017cm-3. Doping characteristics such as the acceptor concentration and the PL properties depend on the gas mixing ratio and the rf power. p-ZnSe layers grown with this technique were used for blue-green laser structures. Lasing was observed at 77 K under pulse operation.
