Abstract

A two-electron quantum disc under harmonic confinement potential and uniform magnetic field normal to surface disc is considered. In this regard, a change of variable is used and the total Hamiltonian is divided into center of mass and relative part Hamiltonians. The Schrodinger equations of each part are analytically solved and wave functions and eigen values energy are obtained. To study the tunneling effect, a constant confinement potential for barrier region is considered and the quantum transmission coefficient in terms of height and barrier width and magnetic field is calculated. Results show the transmission coefficient decreases with increase the height and width barrier and increases with magnetic field
