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 ...

Article Published: 25 November 2014 Electron transfer and coupling in graphene–tungsten disulfide van der Waals heterostructures Jiaqi He, Nardeep Kumar, Matthew Z. Bellus, Hsin-Ying Chiu, Dawei ...

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 ...

The copper target was operated at voltages of 11 kV, 12 kV, 13 kV, and 14 kV for the electron source, and a 50 kV configuration using a molybdenum target was used as a representative example for ...

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 ...

Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics.

A research team of fusion scientists has succeeded in developing 'the nano-scale sculpture technique' to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This ...

Natali Brillianata / Shutterstock The only material that is practically used for electron emitters is tungsten. Although there are other electropositive metals that yield higher emission rates, ...

Though WS2 and WSe2 are similar, they responded differently to the “valley-splitting” exercise. In WS2, the valley that got “deeper” was analogous to the valley in WSe2 that became “shallower,” and ...
