Abstract
Temperature-dependent Hall effect measurements are reported on a serie s of nitrogen doped ZnSe and ZnTe epilayers using a van der Pauw confi guration. A Zn(Se,Te) pseudo-graded band gap layer was used to form oh mic contacts to p-type ZnSe. The activation energy of nitrogen in ZnSe at the infinite dilution limit was extrapolated to be 114 meV. For a ZnTe film having a room temperature free hole concentration of p = 4.1 x 10(16) cm-3, the activation energy of the nitrogen acceptors was fo und to be 46 meV.
