Electron transport through a quantum dot ring
量子点环的电子输运研究

Based on the non-equilibrium Green function formalism, we studied the coherent t ransport through a quantum dot ring. Compared with a one-dimensional quantum dot array, a quantum dot ring presents a number of new quasi-bounding-states in its electronic spectra. Moreover, the enhancement of the inter-dot coupling would l ead to the prominent decoherence of Coulomb-blockade conductance oscillation.
