The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...

The international research team found that excited electrons (at the centre of the image) can straighten out the skewed crystal lattice of perovskite nanocrystals. Many a scientific and technical ...

New measurements in germanium reveal how excited electrons drive lattice vibrations that govern energy flow and heating in semiconductors. (Nanowerk News) Whether in a smartphone or laptop, ...

Schematic illustrations of a persistent luminescence mechanism under (a) band-to-band or (b) below-gap excitation: 1, excitation—electrons are excited and holes generated under illumination; 2, ...
