Electron-hole transition in spherical QD-QW nanoparticles based on GaN∣(In,Ga)N∣GaN under hydrostatic pressure

Within the framework of effective-mass approximation and finite parabolic potential confinement barrier in which two confinement parameters are taking account, the electron (hole) energy and the ground-state electron-hole (e−he−h) transition in Core∣well∣shell (GaN|InxGa1−xN|GaN)(GaN|InxGa1−xN|GaN) spherical QD-QW nanoparticles are investigated as a function of the inner and the outer radii under externally applied hydrostatic pressure. The pressure dependencies of the effective-mass and the QD radius are taking into account. The results we obtained are in quite good agreement with the theoretical and the experimental findings.
