Abstract

In the present study, a tuned quantum dot/ring system under the simultaneous effects of temperature, pressure, and an external magnetic field is investigated. The energy eigenvalues and wave functions are analytically derived using the Laplace transform. Then, an analytical expression for the interband light absorption coefficient is derived. Also, we obtain an analytical expression for the absorption threshold frequency (ATF) of the system. It is observed that (i) the ATF decreases when the pressure rises; (ii) the ATF increases with an increase in the magnetic field and with increasing temperature; and (iii) we can optimize the ATF by varying the pressure, temperature, and magnetic field.
