For 10 points, identify this physicist who lends his name to a low-voltage-drop, fast-switching diode.
The Richardson formula for thermionic emission is modified in the presence of an electric field which lowers the work function in an effect named for this scientist. A device named for this scientist was first realized in the form of the cat's whisker element, and inserting that device between the base and the collector of a BJT results in this scientist's namesake transistor. This scientist is the alphabetically second namesake of a rule which says that the difference between the metal work function and the electron affinity (*) gives the potential difference at the interface between a metal and an n-type semiconductor. That rule, named after this scientist and Mott, gives the height of his namesake barrier at such a junction, which can be used as part of a rectifying element.
