According to the theory of electron tunneling barrier in quantum well structure,the photoelectric properties for GaN-based blue light emitting diodes(LEDs) with different heights,widths of the barrier and quantum well have been simulated by the APSYS software.The calculations of the I-V characteristics,light intensity,internal quantum efficiency at different conditions show that there is a red-shift in the spontaneous emission spectrum.Compared with the conventional quantum well parameters of LE...
