Abstract

A wave function is constructed and the binding energy of electron localized at an ideal quantum dot in the external magnetic field is calculated. It is shown that the energy of the Zeeman splitting in moderate magnetic fields corresponds to photons from the terahertz band, i.e., processes with the electron spin flip lead to radiation or absorption of terahertz radiation. It is established that external terahertz radiation changes the spin equilibrium distribution and, as a result, the magnetization of the system, thus creating the possibility of detection of this radiation by measuring the magnetization of the system of quantum dots.
