The lateral tunneling rate and carrier diffusion in weakly coupled quantum dots are analyzed. In the weak coupling limit, localization of charge within a single dot is obtained through superposition of the lowest-energy eigenstates of coupled dots. The free evolution of the wave function leads to tunneling, but with a time dependence that includes dephasing. Idealized quantum dot boundary conditions are used to estimate tunneling times, and these are compared with recent experiments. © 1998 American Institute of Physics.
