Abstract
Using the effective mass approximation and transfer matrix formalism the ground state energy of an electron in GaAs/Ga1−xAlxAs concentric double quantum rings is calculated taking into account the combined effects of electric field, hydrostatic pressure, temperature and aluminum concentration. The ground state energy dependences on the mentioned factors are presented for different values of the sizes of rings and electric field strength. It is found that the considered effects mainly depend on the dimensions of quantum rings.
