Why is it that atoms have well-defined energy states, but large collections of atoms have broad energy bands? It all has to do with Schrodinger's cat, and the physics of fenced-in dogs.

Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide ...

The band has had only four conductors during its 52-year history -- Fennell (1952-61), A. Clyde Roller (1962-64), Donald Hunsberger (1965-2002) and Mark Davis Scatterday.
