GaN-based semiconductor devices and materials

Heterojunction laser diodes of AlGaAs have been prepared with threshold current densities substantially below those previously achieved at room temperature in the 7200–8000-Å spectral range. These devices operate cw with simple oxide-isolated stripe contacts to 7400 Å, which extends cw operation for the first time into the visible (red) portion of the spectrum.
