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 ...

Why is it that there are certain energies that an electron inside a material simply can not have? Like much of quantum physics, it's all because electrons are waves.

Indium gallium zinc oxide (IGZO)-based displays suffer from instability caused by atomic-scale defects. Now, a new study ...
