摘要
We report on a novel pulsed atomic layer epitaxy (PALE) growth technique for quaternary AlInGaN films for ultraviolet optoelectronics applications. Using the PALE approach, quaternary AlInGaN/AlInGaN multiple quantum wells (MQWs) were successfully gown over sapphire substrates. These were characterized using X-ray diffraction, atomic force microscopy, and photoluminescence to establish structural and optical quality. Incorporating the PALE grown quaternary MQWs as the active layer we also demonstrated ultraviolet electroluminescence at 343 nm with an output power up to 0.12 mW at room temperature.
