| 英文摘要 | For a triangular triple quantum dots (ttqds) ring with three terminals, when lowering one of the dot-lead coupling to realize the left-right (l-r) reflection symmetry coupling, the internal c-upsilon of the ttqds is well preserved in the absence of many-body effect for the symmetric distribution of the dot-lead coupling on the molecular orbits. in the presence of kondo effect, the decrement of one of the dot-lead couplings suppresses the inter-dot hopping. this happens especially for the coupled quantum dot (qd), which decouples with the other two ones gradually to form a localized state near the fermi level as a result, the internal dynamic symmetry of the ttqds ring is reduced to l-r reflection symmetry, and simultaneously, the linear conductance is lifted for the new forming molecular orbit near the fermi level (c) 2010 elsevier ltd all rights reserved |
