work function

noun Physics

The minimum quantity of energy which is required to remove an electron to infinity from the surface of a given solid, usually a metal. (Symbol: φ) The energy required to remove an electron from the metal is called the work function, which is written as hv (Planck's constant multiplied by the required frequency of light)....

When we heard that a filament of platinum - which, like tungsten, is a metal with a high work function - tended to show less positive-ion noise, Sheldon obtained a sample.
The high current density is possible because the p-doped WBG region acts as a negative electron affinity material when in contact with low work function metals.
