There is no such thing as a Schottky transistor per se BUT they are
used to speed up switching of conventional transistors by stopping
them going into deep saturation - have a look at the internal circuit
of any 74LSxx (low power Schottky) or 74Sxx (High power :-) Schottky)
logic IC. A bit old tech now :-).
