Abstract
AbstractThe Kondo effect has been widely studied in semiconductor quantum dots, in particular due to the ability to study the system out‐of‐equilibrium. However, the information obtained from a quantum dot connected to two leads is not complete, and a better understanding of this regime can be achieved by connecting the system to a third lead. We have performed transport measurements on a three‐terminal quantum ring in the Kondo regime. With two leads strongly coupled to the ring, we have used the third weakly coupled lead as a tunnel probe in order to measure the Kondo density of states, and to study the decoherence of the Kondo state at large bias voltage. We also show that the three leads can be strongly coupled and all show a Kondo correlation with the ring, which is the first step towards observing a two‐channel Kondo effect.
