A transfer Hamiltonian approach for an arbitrary quantum dot array in the self-consistent field regime

A transport methodology to study electron transport between quantum dot arrays based on the transfer Hamiltonian approach is presented. The interactions between the quantum dots and between the quantum dots and the electrodes are introduced via transition rates and capacitive couplings. The effects...
