RESONANT TUNNING THROUGH QUANTUM DOT ARRAY

ABSTRACT

This research work as aimed at calculating the resonant tunnelling energy of a quantum dot array which is the energy needed by a particle to tunnel through multiple barrier. A Hamiltonian of the form;

H

Was use to act on some states with different spin orientations to obtain four by four matrices. The Eigen value which was obtained can further be use to calculated the conductance in transition of the particle.
