| Abstract: | We report about Zn diffusion experiments at 700–850°C in (AlGa)P hetero-structures grown by liquid-phase epitaxy. The effective diffusion constant Al0.35Ga0.65P is found to be 10–50 times larger than in GaP and has a smaller activation energy. We discuss the implication of this for device work and give a tentative explanation. |
