| 英文摘要 | We present a theoretical description for electron transport through an Aharonov-Bohm ring with a quantum dot side-coupled to one arm. An analytic formula of conductance is derived which shows the Aharonov-Bohm oscillations. The quantum dot modulates electron transmission through the coupled arm, and thus affects the amplitude of the AB oscillations. Tuning the plunger gate of the quantum dot can induce the antiresonance, in which the transmission through the coupled arm is quenched and the Aharonov-Bohm oscillations are suppressed completely. The temperature-dependence of the suppression of the Aharonov-Bohm oscillations is discussed. (c) 2005 Elsevier B.V. All rights reserved. |
