Studies from Research Institute Provide New Data on Low Dimensional Structures (Design of deep ultraviolet light-emitting diodes with staggered AlGaN quantum wells)

By a News Reporter-Staff News Editor at Physics Week -- Investigators discuss new findings in Low Dimensional Structures. According to news reporting from Hefei, People's Republic of China, by VerticalNews journalists, research stated, "The AlGaN-based deep ultraviolet light-emitting diodes (UV LEDs) with specific design of staggered AlGaN quantum wells are investigated numerically."

The news correspondents obtained a quote from the research from Research Institute, "The proposed UV LEDs with Al0.45Ga0.55N-Al0.5Ga0.5N Al0.45Ga0.55N and Al0.5Ga0.5N-Al0.45Ga0.55N-Al0.5Ga0.5N staggered quantum well layers exhibit significant improvement for the light output power and carrier injection efficiency compared with the conventional AlGaN UV LED."

According to the news reporters, the research concluded: "The enhanced performance of the designed LEDs is explained by the simulated distribution of carrier concentration, radiative recombination rate and wave function overlap in the quantum wells."
