Ballistic transport occurs whenever electrons propagate without collisions deflecting their trajectory. It is normally observed in conductors with a negligible concentration of impurities, at low ...

A single platinum nanoparticle observed by electron holography. (Courtesy: Murakami Lab, Kyushu University) How many electrical charges does a platinum nanoparticle have? Thanks to an improved ...

A ‘hole’ arises due to a missing electron in the valence band, which normally participates in covalent bonding between atoms. The absence of an electron creates a local absence of a negative charge, ...

Alexey Petrov receives funding from US Department of Energy. What is the shape of an electron? If you recall pictures from your high school science books, the answer seems quite clear: an electron is ...

Researchers demonstrated the direct counting of small electric charges in individual catalyst nanoparticles. Ultrahigh sensitivity and precision electron holography improved by the developed noise ...
