摘要：

Bandgap tuning by impurity-free vacancy disordering was investigated on carbon and zinc p-doped laser structures. Zinc diffused during annealing and consequently only carbon-doped material lased. After annealing, threshold current densities rose from 225 to 255 A cm(-2) due to an increase in the transparency current; the gain constant of the quantum wells remained constant.
