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-motion part Hamiltonians. The Schrodinger equations of each part are analytically solved, and the wave functions and the eigen values energy are obtained. To study the tunneling effect, a constant confinement potential for the barrier region is considered, and the quantum transmission coefficient is calculated in terms of height and barrier width and magnetic field. Results show that the transmission coefficient decreases with increasing height and width barrier, and increases with the magnetic field.
