Abstract

Using the effective mass approximation and finite element method numerical calculations, optical, and electronic properties of an electron confined in a GaN quantum dot are reported for a spherical conical sector. Electronic states, the square of the dipole moment, optical absorption coefficients, and changes in the refractive index are reported as functions of the radius and the apical angle of the structure. From the study it can be concluded that: i) suitable choices of the apical angle and the radius of the quantum dot can give rise to magnifications in the optical properties and ii) redshifts of the resonant structures of the optical properties are clearly associated with the increase in both the apical angle and the radius of the structure.
