We report here on a direct and non-invasive measurement of the charge and its distribution in a Kondo correlated quantum dot (QD). A non-invasive potential-sensitive detector in proximity with the QD reveals that even though the conductance of the QD is significantly enhanced as it enters the Kondo regime the net charge in the QD remains unaffected. This demonstrates the separation between spin and charge degrees of freedom in the Kondo effect. We find however, under certain experimentaldoi:10.1103/physrevlett.88.176805 pmid:12005776 fatcat:rnyi7v5usbbx3ft35qiv5w6rnm
