Abstract
We investigate the resonant tunneling in an Aharonov-Bohm ring with a quantum dot embedded in one of its arms. A complete transmission mecha nism, considering both the resonance of the dot and the interference e ffect, is presented. As a consequence, the experimental results, the p hase features for conductance peaks, are well explained by a one-dimen sional noninteracting model. New features concerning temperature effec ts are predicted.
