摘要：

We report excited-state spectroscopy on a quantum dot side coupled to a quantum wire with accurate energy estimation. Our method utilizes periodic voltage pulses on the dot, and the energy calibration is performed with reference to the bias voltage across the wire. We demonstrate the observation on the orbital excited state and the Zeeman splitting in a single dot. (C) 2008 American Institute of Physics.
