Temperature Effects of Electric Field on the First Excited State of Strong Coupling Polaron in a CsI Quantum Pseudodot

Employing variational method of Pekar type（VMPT）, this paper investigates the first-excited state energy（FESE）, excitation energy and transition frequency of the strongly-coupled polaron in the Cs I quantum pseudodot（QPD）with electric field. The temperature effects on the strong-coupling polaron in...

More Information
Summary:Employing variational method of Pekar type（VMPT）, this paper investigates the first-excited state energy（FESE）, excitation energy and transition frequency of the strongly-coupled polaron in the Cs I quantum pseudodot（QPD）with electric field. The temperature effects on the strong-coupling polaron in electric field are calculated by using the quantum statistical theory（QST）. The results from the present investigation show that the FESE, excitation energy and transition frequency increase（decrease） firstly and then at lower（higher） temperature regions. They are decreasing functions of the electric field strength.
