The recombination of electron shells in molecules, taking just a few dozen attoseconds (a billionth of a billionth of a second) can now be viewed 'live,' thanks to a new method. The recombination of ...

(Nanowerk News) The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks directly, but rather by their ...

A strong electron–hole exchange interaction (EI) in semiconductor nanocrystals (NCs) gives rise to a large (up to tens of meV) splitting between optically active ('bright') and optically passive ...

Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...
