Abstract
By developing the rate equation method, we study the transport properties of a three-terminal triple quantum dot system in the presence of a perpendicular magnetic field. It is shown that the inter-dot coupling between two quantum dots, which contacted with two drains, brings a “sticking” effect and causes decay in the source-drain current, and localization of electrons. We also investigate the coexistence and interplay of multiterminal interference and Aharonov-Bohm (AB) effects under the condition of two output terminals. Furthermore, we found that the fundamental periodic oscillation in the I-flux curves would weaken with the increase in magnetic field frequency.
