Abstract
We investigate transport via sequential tunneling through a semiconductor double quantum dot structure by combining a simple one-dimensional microscopic quantum confinement model with a Mott-Hubbard-type correlation model. We calculate nonperturbatively the evolution of the Coulomb blockade oscillations as a function of the interdot barrier conductance, obtaining qualitative agreement with the experimental data over the whole tunneling regime from the weak-coupling individual dot to the strong-coupling coherent double-dot molecular system.Keywords
