Abstract:

We measure single electron movement between two coupled quantum dots each isolated from a reservoir. The electrons movement is detected using a 1-D channel placed next to the double dot system. The electrostatic energy required to move an electron from one dot to a reservoir is half that required to move the electron from one dot to the other dot. We estimate the maximum intra-dot scattering time at < 0.2 ns. This scattering time corresponds to a lifetime broadening equal to the thermal broadening (80 mK) indicating that the scattering time may be longer than this. © 2002 Elsevier Science B.V.
