Non-contact atomic force microscopy (nc-AFM) offers a unique experimental framework for topographical imaging of surfaces with atomic and/or sub-molecular resolution. The technique also permits to perform frequency shift spectroscopy to quantitativel

Scanning gate measurements have been performed on a shallow two-dimensional electron gas in a Ga[Al]As heterostructure in the quantum Hall regime at 300 mK . This technique uses the local electrostatic potential induced by the conducting tip of a sca

We investigate the magnetoresistance of a side-gated ring structure etched out of single-layer graphene. We observe Aharonov-Bohm oscillations with about 5% visibility. We are able to change the relative phases of the wave functions in the interferin

In this paper we apply scanning probe techniques to a QPC patterned with the local anodic oxidation technique on the 2DEG in a GaAs heterostructure. We use the conducting tip of a scanning force microscope as a local gate and measure the conductance

Low-temperature transport experiments on a quantum point contact under the influence of a scanning gate are reported. The scanning gate is the metallic tip of a scanning force microscope operating at a temperature of 300 mK. In particular, the influe

Scanning-gate imaging of semiconductor quantum dots (QDs) promises access to probability distributions of quantum states. It could therefore be a novel tool for designing and optimizing tailored quantum states in such systems. A detailed study of a l

A two-dimensional electron gas in the quantum Hall regime has been investigated by tuning the local potential with the metallic tip of a scanning force microscope. The longitudinal four-terminal resistance of the Hall bar structure was recorded while

The scanning metallic tip of a scanning force microscope was coupled capacitively to electrons confined in a lithographically defined gate-tunable quantum dot at a temperature of 300 mK. Single electrons were made to hop on or off the dot by moving t
