Study of the effect of magnetic field on the impurity bound polaronic energy levels in a parabolic quantum dot

The problem of interface optical polaron, bound to an impurity atom in a parabolic quantum dot near the semiconductor heterostructure has been investigated in the framework of canonical transformation method. An external magnetic field is applied in the growing direction of the quantum dot heterostructure (along the z-direction). A calculation has been proposed to study the dependence of the ground state energy on the magnetic field and the thickness of the well. The binding energy and hence the quantum confinement increases with the increasing magnetic field. The effect of the thickness on the induced potential and hence on the ground state energy has also been studied.
