Abstract

Electronic transport through a two-path triple-quantum-dot system with two source leads and one drain is studied and the interaction between the two paths is analyzed. We observe a channel blockade as a result of interchannel Coulombic interaction. The experimental results are understood with the help of a theoretical model which allows one to obtain the parameters of the system, the stability regions of each state, and the full dynamical transport in the triple-dot resonances.
