摘要: The transport properties of a metal core/semiconductor shell quantum dot molecule (QDM) embedded in a matrix connected to metallic electrodes are theoretically studied in the framework of Keldysh Green function technique. The effects of the electron plasmon interactions (EPIs) on the tunneling current spectra of QDM are examined. The energy levels of the QDs, intradot and interdot Coulomb interactions, electron interdot hopping strengths, and tunneling rates of QDs are renormalized by the EPIs. The differential conductance spectra show peaks arising from the plasmon assisted tunneling process, intradot and interdot Coulomb interactions, and coherent tunneling between the QDs. 出版者: The Japan Society of Applied Physics 出版日期: 2013-06-01 出處: Japanese Journal of Applied Physics, 2013-06, Vol.52 (6), p.065001-065001-4 資源來源: IOP Journals 識別號: ISSN: 0021-4922 識別號: EISSN: 1347-4065 識別號: DOI: 10.7567/JJAP.52.065001
