摘要
p-type ZnSe with resistivity low enough for device application has been realized by metalorganic molecular beam epitaxy. This method has enabled growth of p-type ZnSe doped with nitrogen at concentrations as high as 1019 cm-3 by using ammonia as a dopant source. The dependence of photoluminescence and electrical properties on substrate temperature has been investigated. Hall measurements show p-type conductivity with a resistivity of 0.57 Ω cm, a carrier concentration of 5.6×1017 cm -3, and a Hall mobility of 20 cm2/V s.
