The invention of scanning tunneling and atomic force probes revolutionized our
understanding of surfaces by providing real-space information about the geometric and …

Quantum dots provide a natural system in which to study both quantum and classical
features of transport. As a closed testbed, they provide a natural system with a very rich set …

Combining scanning gate microscopy (SGM) experiments and simulations, we demonstrate
low temperature imaging of the electron probability density| Ψ| 2 (x, y) in embedded …

Scanning gate microscopy (SGM) is used to image scar structures in an open quantum dot,
which is created in an InAs quantum well by electron-beam lithography and wet etching. The …

The inverse problem of estimating the background potential from measurements of the local
density of states is a challenging issue in quantum mechanics. Even more difficult is to do …

Scanning gate microscopy (SGM) is a valuable scanning probe technique for characterizing
electronic transport in mesoscopic systems. However, the interpretation of the method is …

We study the relationship between the local density of states (LDOS) and the conductance
variation Δ G in scanning-gate-microscopy experiments on mesoscopic structures as a …

We use scanning gate microscopy to probe the ballistic motion of electrons within an open
GaAs/AlGaAs quantum dot. Conductance maps are recorded by scanning a biased tip over …

We theoretically study scanning gate microscopy (SGM) of electron and hole trajectories in a
quantum point contact (QPC) embedded in a normal-superconductor (NS) junction. At zero …

We perform scanning-gate microscopy on a quantum-point contact. It is defined in a high-
mobility two-dimensional electron gas of an AlGaAs/GaAs heterostructure, giving rise to a …
