With the adoption of a plasma activated nitrogen source,the net hole concentration in ZnSe could be raised up to~1×1018 cm-3, a value which is almost an order of magnitude higher than what the conventional doping technique cOuld reach. Nevertheless, the plasma nitrogen source is too expensive for the Chinese laboratories to consume. We report here a simplified plasma nitrogen source which could be used in the MBE doping of p-ZnSe: N, whose principle part is a quartz tube. The source is activated by means of...
