Scanning gate microscopy of electron flow from a spin-orbit
... Scanning gate microscopy (SGM) is a technique that allows for spatial mapping of current flow and charge densities in semiconductor nanostructures. This technique has been used to map electron flow from a constriction introduced in a quantum channel – quantum point contact (QPC). The experiments obser ...
