Аннотация
Hydrogen-like donor impurity states in a quantum well with modified Pöschl-Teller confinement potential have been considered. The dependence of binding energy on hydrogen-like donor impurity position and confinement potential parameters has been revealed. It has been shown that the dependence of binding energy on hydrogen-like donor impurity position has the bell-shaped character. The existence of binding energy maximum is explained by the concurrency of the size-quantization effect and the Coulomb interaction between electron and hydrogen-like donor impurity. The coefficient of an optical absorption in the presence of hydrogen-like donor impurity center has been computed. The absorption spectra for the quantum transitions between the hydrogen-like donor impurity ground state and conduction band ground state have been obtained.
