Gate current

Ulbricht, W., Ionic channels and gating currents in excitable membranes, Ann. Rev. Biophys. Bioeng., 6, 7 (1977). 

Field-effect transistors (FETs) have dominated the semiconductor industry, largely displacing the earlier bipolar junction transistor (BJT) because of its negligible gate current and convenience in the design of integrated circuits. Figure 29 sketches how an FET works.

Figure 15-28 Operation of a field effect transistor, (a) Nearly random distribution of holes and electrons in the base in the absence of gate potential. ( >) Positive gate potential attracts electrons that form a conductive channel beneath the gate. Current can flow through this channel between source and drain.
