摘要: The optical properties of blue-violet InGaN lightemitting
diodes under normal and reversed polarizations are
numerically studied. The best light-emitting performance
under normal and reversed polarization is obtained in a
single quantum-well structure and double quantum-well
structure, respectively. The key factors responsible for these
phenomena are presumably the carrier concentration distribution
and the amount of carriers in quantum wells. The turnon
voltage of light-emitting diodes under reversed polarization
is lower than that of light-emitting diodes under normal
polarization, due mainly to lower potential heights for electrons
and holes in the active region.
