Gating a Quantum Dot through the Sequential Removal of Single Electrons from a Nanoscale Floating Gate
We use the tip of an atomic force microscope (AFM) to charge floating metallic gates defined on the surface of a Si/SiGe heterostructure. The AFM tip serves as an ideal and movable cryogenic switch, allowing us to bias a floating gate to a specific voltage and then lock the charge on the gate by wit...
