To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, among other things, because they lead ...

Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny those transistors can get.

A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band ...

Silicon’s performance as a semiconductor, however, leaves much to be desired. The issues with the material are twofold. The first concerns the mobility of its “holes”, which are regions of positive ...
