Electron microscopy based on high-energy electrons allows nanoscopic analytical imaging taking advantage of secondarily generated particles. Especially for cathodoluminescence, the correlation between ...

Free electrons are essential in such diverse applications as electron microscopes, accelerators and photoemission spectroscopy. However, the space charge effects of many electrons are often a problem ...

In order to overcome this resistance, it would require an extra boost of energy—just enough to overcome the electron's natural repulsion. The team reasoned that the magnitude of this boost would be a ...

Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a ...

Beijing Zhongke Journal Publising Co. Ltd. Heavy fermion materials have long attracted interest in condensed matter physics for hosting correlation-driven exotic quantum states. Remarkably, the oxide ...

If electron correlations have any effect, such perturbations of electron configurations would meet resistance, since electrons naturally repel each other. For example, an electron that attempts to ...

In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a ...
