Coulomb-Modified Fano Resonance in a One-Lead Quantum Dot
A. C. Johnson, C. M. Marcus, M. P. Hanson +1
We investigate a tunable Fano interferometer consisting of a quantum dot coupled via tunneling to a one-dimensional channel. In addition to Fano resonance, the channel shows strong…

Differential Charge Sensing and Charge Delocalization in a Tunable Double Quantum Dot
L. DiCarlo, H. J. Lynch, A. C. Johnson +5
We report measurements of a tunable double quantum dot, operating in the quantum regime, with integrated local charge sensors. The spatial resolution of the sensors is sufficient t…
