Abstract(in English) | The external quantum efficiencies of AlGaN-based deep ultraviolet light emitting diodes are less than 5%, due to the causes such as low hole concentration in p-type AlGaN. To avoid problems associated with p-type AlGaN and to obtain the deep ultraviolet emission with high power and efficiency, high-quality Al-rich AlGaN/AlN quantum wells were pumped by an electron beam. An output of 100 mW and a power efficiency of 40% have been achieved at a wavelength of about 240 nm by optimizing both the electron beam condition and the quantum well structure. |
