The Quantum Twisting Microscope [PDF]
, 2022 The invention of scanning probe microscopy has revolutionized the way electronic phenomena are visualized. While present-day probes can access a variety of electronic properties at a single location in space, a scanning microscope that can directly probe the quantum mechanical existence of an electron at multiple locations would provide direct access ...

Quantum-coherent light-electron interaction in an SEM [PDF]
, 2021 The last two decades experimentally affirmed the quantum nature of free electron wavepackets by the rapid development of transmission electron microscopes into ultrafast, quantum-coherent systems. In particular, ultrafast electron pulses can be generated and timed to interact with optical near-fields, yielding coherent exchange of the quantized photon ...

Microscopic origin of molecule excitation via inelastic electron scattering in scanning tunneling microscope [PDF]
New Journal of Physics 22, 113010 (2020), 2020 The scanning-tunneling-microscope-induced luminescence emerges recently as an incisive tool to measure the molecular properties down to the single-molecule level. The rapid experimental progress is far ahead of the theoretical effort to understand the observed phenomena.

Closed-Loop Autofocus Scheme for Scanning Electron Microscope
MATEC Web of Conferences, 2015 In this paper, we present a full scale autofocus approach for scanning electron microscope (SEM). The optimal focus (in-focus) position of the microscope is achieved by maximizing the image sharpness using a vision-based closed-loop control scheme.

Scan Coil Dynamics Simulation for Subsampled Scanning Transmission Electron Microscopy [PDF]
arXiv, 2023 Subsampling and fast scanning in the scanning transmission electron microscope is problematic due to scan coil hysteresis - the mismatch between the actual and assumed location of the electron probe beam as a function of the history of the scan. Hysteresis limits the resolution of the microscope and can induce artefacts in our images, particularly ...
