Secondary electron emission (SEE) is a fundamental physical process whereby incident electrons or photons induce the ejection of electrons from a material’s surface. This phenomenon has significant ...

To simplify the electron emission mechanism involved in microwave electron guns, a team of researchers has created and demonstrated a field-emission plug-and-play solution based on ...

The way electrons interact with photons of light is a key part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently a weak one because of a major ...

TOKYO--(BUSINESS WIRE)--JEOL Ltd. (TOKYO:6951) (President & COO Izumi Oi) announced that it has developed semi-in-lens versions (i)/(is) which are optimal for the observation of semiconductor devices ...

When light hits a material, electrons can be released from this material -- the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds ...

Free electrons are those not bound to a specific atom or molecule, wondering freely within a material. They play a vital role in a wide range of applications, from photoreactors and microscopes to ...

Researchers at University of Tsukuba have demonstrated that graphitizing the fractured surface of a mechanical pencil lead enables the easy creation of axially oriented graphene edges, which serve as ...

Researchers have found a way to create much stronger interactions between photons and electrons, in the process producing a hundredfold increase in the emission of light from a phenomenon called Smith ...
