Structural Designof AlGaN Deep-Ultraviolet Laserat Wavelength 266.3 nm with Graded Electron Blocking Layer and CompositeQuantum Wells/Barriers

Abstract Deep-ultraviolet laser diodes (DUV LDs) are developing as vigorous light sources for sterilization, lithography, purification, and biochemical sensing. However, the development of high-performance deep-UV laser diodes is still limited by poor hole injection, which comes...
