Partial Scanning Transmission Electron Microscopy with Deep Learning [PDF]
Sci Rep 10, 8332 (2020), 2019 Compressed sensing algorithms are used to decrease electron microscope scan time and electron beam exposure with minimal information loss. Following successful applications of deep learning to compressed sensing, we have developed a two-stage multiscale generative adversarial neural network to complete realistic 512$\times$512 scanning transmission ...

Formation of Three-Way Scanning Electron Microscope Moiré on Micro/Nanostructures
The Scientific World Journal, 2014 Three-way scanning electron microscope (SEM) moiré was first generated using a designed three-way electron beam (EB) in an SEM. The spot-type three-way SEM moiré comes from the interference between the three-way EB and the specimen grating in which the ...

Imaging doubled shot noise in a Josephson scanning tunneling microscope [PDF]
Phys. Rev. B 100, 104506 (2019), 2019 We have imaged the current noise with atomic resolution in a Josephson scanning tunneling microscope with a Pb-Pb junction. By measuring the current noise as a function of applied bias, we reveal the change from single electron tunneling above the superconducting gap energy to double electron charge transfer below the gap energy when Andreev processes ...

A case of trichorrhexis nodosa
Pifu-xingbing zhenliaoxue zazhi, 2022 We report a case of trichorrhexis nodosa. A 27-year-old female presented with white nodules of hair that were easily broken for 17 years. Dermatological examination showed that the hair was sparse, dry, and there were many tiny granular white nodules ...

Scanning electron microscopy image representativeness: morphological data on nanoparticles. [PDF]
, 2017 A sample of a nanomaterial contains a distribution of nanoparticles of various shapes and/or sizes. A scanning electron microscopy image of such a sample often captures only a fragment of the morphological variety present in the sample.

The trajectories of secondary electrons in the scanning electron microscope [PDF]
Scanning, 2006 AbstractThree‐dimensional simulations of the trajectories of secondary electrons (SE) in the scanning electron microscope have been performed for plenty of real configurations of the specimen chamber, including all its basic components. The primary purpose was to evaluate the collection efficiency of the Everhart‐Thornley detector of SE and to reveal ...
