A Simple Scanning Electron Microscope [PDF]
Review of Scientific Instruments, 1969 A simple scanning microscope has been built which uses a field emission electron gun alone, without the aid of auxiliary lenses. The design and operation of the microscope are described and the calculated performance is compared with experiment. Resolution of 100 Å has been obtained and is shown in transmission electron micrographs.

A scanning electron microscope for ultracold atoms [PDF]
Laser Physics Letters, 2006 We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focused electron probe. Subsequent detection of the resulting ions allows for the reconstruction of the atom's position.

A scanning electron microscopic study of hypercementosis [PDF]
Journal of Applied Oral Science, 2008 The purpose of this study was to evaluate morphological characteristics of teeth with hypercementosis that are relevant to endodontic practice. Twenty-eight extracted teeth with hypercementosis had their root apexes analyzed by scanning electron microscopy (SEM). The teeth were divided according to tooth groups and type of hypercementosis.

Cathodoluminescence studies of phosphors in a scanning electron microscope [PDF]
, 2015 Cathodoluminescence studies are reported of phosphors in a field emission scanning electron microscope (FESEM). A number of phosphor materials have been studied and exhibited a pronounced comet-like structure at high scan rates, because the particle ...

A fluorescence scanning electron microscope
Ultramicroscopy, 2009 Fluorescence techniques are widely used in biological research to examine molecular localization, while electron microscopy can provide unique ultrastructural information. To date, correlative images from both fluorescence and electron microscopy have been obtained separately using two different instruments, i.e.

Mechanical scanning of the specimen in the scanning electron microscope [PDF]
Scanning, 2004 AbstractA scanning electron microscope (SEM) system equipped with a motor drive specimen stage fully controlled with a personal computer (PC) has been utilized for obtaining ultralow magnification SEM images. This modern motor drive stage works as a mechanical scanning device.

Nitrogen implantation with a scanning electron microscope [PDF]
Scientific Reports, 2018 AbstractEstablished techniques for ion implantation rely on technically advanced and costly machines like particle accelerators that only few research groups possess. We report here about a new and surprisingly simple ion implantation method that is based upon a widespread laboratory instrument: The scanning electron microscope.

Nanotip electron gun for the scanning electron microscope [PDF]
Scanning, 2005 Experimental nanotips have shown significant improvement in the resolution performance of a cold field emission scanning electron microscope (SEM). Nanotip electron sources are very sharp electron emitter tips used as a replacement for the conventional tungsten field emission (FE) electron sources.
