摘要: The concept of a step-like quantum well is
proposed with the purpose to reduce the influence of
electrostatic field resulting from the piezoelectric effect
on the optical performance of blue InGaN light-emitting
diodes. Particularly, the optical properties of the LED
structures with the In0.23Ga0.77N single quantum well,
In0.20Ga0.80N/In0.26Ga0.74N step-like quantum well, and
In0.26Ga0.74N/In0.20Ga0.80N step-like quantum well are numerically
investigated in detail. Simulation results show that
the In0.20Ga0.80N/In0.26Ga0.74N step-like-quantum-well
LED structure has the best optical performance in virtue
of the improvement in spatial overlap of electrons and holes
in the quantum well.
