Charge control

Charge control

We can attach single electron charges to molecules and atoms using the tip of the microscope [1].

Using Kelvin probe force microscopy, we detect atomic charge states [2,3] and molecular charge distributions [4].

We are interested in controlling and measuring single electron charge transfer between molecules [5] and ultimately within molecule–metal networks on surfaces.
