These devices have NPN or PNP junctions, which can create depletion regions to make opposing diodes.
One variation of this device consists of a junctionless nanowire surrounded by an electrically isolated "wedding ring." In one variant of this device, a carbon nanotube creates a Schottky barrier which relies on quantum mechanical tunneling. Parameters like transport saturation current are tracked in their Gummel- Poon model. NAND and NOR logic gates are made of these devices combined in (*) "pull up" and "pull down" networks. These devices have NPN or PNP junctions, which can create depletion regions to make opposing diodes. Bipolar ones posses emitter, collector, and base terminals, while field effect ones have gate, source, and drain terminals. Moore's Law predicts that the amount of these things in an integrated circuit will double every 18 months. For 10 points, name these devices made out of semiconductors which are used as amplifiers and switches.
