Влияние Внешнего Электрического Поля И Диссипативного Туннелирования На Фотолюминесценцию Квантовой Молекулы С Резонансным U-Состоянием2 D -Центра

In the model of a zero-radius potential, the article studies the influence of an external electric field on the photoluminescence of a quantum molecule, which is connected with the electron radiative transition from U-state to g-term of D -center under conditions of dissipative tunnelling.The photoluminescence probability is shown to increase approximately by two orders when the external electric field strength causes the initially asymmetric double-well oscillatory potential (simulating the quantum molecule) to become a symmetric one. The photoluminescence probability has been shown to be highly sensitive to such parameters of dissipative tunneling as temperature, frequency of phonon mode, and the heat-bath interaction constant.
