Abstract
A planar doped valley field effect transistor (PDVFET), which positions more than one two-dimensional electron gas (2DEG) layer within a homo-structure (GaAs), in order to improve the FET's power output. The FET includes two 2DEG donor planes with an undoped GaAs layer therebetween, and a n-doped GaAs layer on the other side of each donor plane. The FET also includes a 2DEG acceptor plane below the n-doped GaAs layer, which is furthest from the contacts. This 2DEG plane combination forms a deep and wide valley in the FET's conduction band, which improves the FET's power output.
