Advances in electron optics have enabled the imaging ... In the mid-1990s, a new generation of commercial field-emission TEMs with scanning attachments made STEM techniques widely available ...

Combine field emission SEM (FE-SEM) technology with advanced analytics. Profit from proven Gemini electron optics. Choose from a variety of detector options: you can image particles, surfaces ...

This means that each electron transition will produce a photon of a different frequency and hence a different colour. This causes line emission spectra to be produced, as shown below. This is not ...

Researchers at Wuhan University recently observed amplified spontaneous emission originating from degenerate electron-hole ...

The instrument is a dedicated field emission, wavelength dispersive electron microprobe (EPMA). Quantitative elemental data can be obtained from most elements (Fluorine to Uranium) with detection ...

Secondary electron images of volcanic ash from a volcanic plume in the crater rim of Villarrica volcano, Chile, collected using an air filter. Scale bars - 1μm. The Ultra Plus scanning electron ...

This creates vacancies, leading to a cascade of electron transitions within the atom as electrons from higher energy levels drop down to fill the vacancy. The energy released during these transitions ...
