摘要：

An ultraviolet light emitting diode with quaternary AlInGaN/AlInGaN multiple quantum wells and peak emission wavelength at 305 nanometers (nm) is reported for the first time. The peak emission wavelength call be tuned front 305 nm to 340 nm by varying the allow compositions of the quaternary AlInGaN active layers using a Pulse atomic layer epitaxy process. At 340 nm, for a 20 /ml x 1000 mum stripe geometry device an output power as high as 1 mW was measured from the sapphire substrate side.
