We propose a scheme for controlling the coherent transport of a single electron through a dosed three-level structure in coupled quantum dots.The coherent transport is exteally controlled by applying a weak few-cycle pulse with an adjustable carrier-envelope phase (CEP).It is revealed numerically that there exists a significant dependence of the electron transport on the CEP.Our results illustrate the potential to utilize few-cycle pulses for the excitation in coupled quantum dot systems through control of the CEP,as well providing guidance in the design for possible experimental implementations.
