Abstract: He+-ion irradiation was applied for electrical isolation of p-In0.49Ga0.51P in InGaP/GaAs/InGaAs structures. Sheet resistance of approximately 1x10(6) Omega/square was achieved with doses above 1x10(13) cm(-2) at 100 keV. Thermal stability of isolation was maintained for annealing temperatures up to 500 degreesC. Photoluminescence results show that InGaP transparency to InGaAs/GaAs quantum-well emission is closely related to sheet resistance changes in the irradiated structure.
