Popis: We describe transport measurements in a novel dual-gated single electron transistor based on a quantum dot (QD) fabricated by selective area growth of metalorganic vapor phase epitaxy. We observed, for the :rst time, clear Coulomb oscillations fabricated in combination with direct growth and lithographically de:ned metal gates, and achieved nearly independent control of the QD potential and the tunneling barrier height. We also were able to observe a signature of Kondo resonance when the coupling between leads and a quantum dot was su
