The latest models of tabletop SEMs (TT-SEMs) feature a range of electron sources. Although a tungsten filament is used in a majority of TT-SEMs, certain models come with a Cerium Hexaboride (CeB6) ...

Unusual electron sharing found in cool crystal Date: July 31, 2020 Source: Nagoya University Summary: Tungsten atoms are seen to come together in a way that is similar to an outer space ion. The ...

In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary ...

Now, for no other reason than wanting a real challenge, the 28-year-old engineer picked the toughest DIY project he could imagine: a homemade scanning electron microscope, or SEM.

To find it, the researchers turned to electron microscopy, to watch how a charge moved through niobium tungsten oxide (NbWo) crystals. They found that the structure of the crystals had a major ...

The shortest electron pulses ever made in the lab have been claimed by researchers in Germany. By firing ultrashort laser pulses at a tungsten nanotip, the team created electron pulses just 53 ...
