Abstract: In this paper, theoretical analysis for the performance of the AlGaN light emitting diodes with different barrier heights was studied. Due to the
polarization charges existed at the well-barrier interface, the electrons and holes were separated in spatial. With the rise of the Al composition in the barrier, this polarization effect is enhanced and the electron-hole recombination rates were thus reduced. As a result, the optimum structure for AlGaN LED is to use one QW and the barrier with small Al composition.
