Abstract

In a method of making a semiconductor device, a p-type compound semiconductor layer containing zinc as a dopant impurity and including at least one transition metal element selected from the group consisting of Fe, V, Cr, Mn, Co, and Ni is grown on a second semiconductor layer, the at least one transition metal element inhibiting zinc from diffusing into the second semiconductor layer. A method of making a semiconductor laser includes growing the p-type compound semiconductor layer containing zinc as a cladding layer and the second layer is an undoped compound semiconductor active layer.
