Abstract

This paper investigates the fully coupled piezoelectric models for determining strain fields, piezoelectric potentials, and optical properties of wurtzite InGaN quantum dots (QDs). Through the calculations, we find that the semi-coupled model clearly overestimates the piezoelectric potential, and the transition energy difference increased with increases in the dot size and indium composition. Consequently, the semi-coupled model causes a great amount of distortion in predicting the optical properties of InGaN QDs, compared to the fully coupled piezoelectric models.
