Eff ect of time dependent electric field on quantum dot in the presence of impurity and magnetic field

The interest in the study of the physical properties o f the confin ed quantum systems such as quant um wells, wires and dots has increased with the recent progress in semicond uctor nanot echnology. Quantum size effects i n these structures, lead to formation of atomic-like discrete energy levels. Recently, investigation of the impurity o n the electro nic structure and transport properti es of QDs has motivated the attenti on of many researchers [۱]. In this paper, the re sponse of system to external sinusoidal electric field is inves tigated.
