Compound semiconductor material is irradiated with x-ray radiation to activate a dopant material. Active carrier concentration efficiency may be improved over known methods, including conventional thermal annealing. The method may be employed for III-V group compounds, including GaN-based semiconductors, doped with p-type material to form low resistivity p-GaN. The method may be further employed to manufacture GaN-based LEDs, including blue LEDs, having improved forward bias voltage and light-emitting efficiency.
