Schottky Wrap Gate Control of Semiconductor Nanowire Networks for Novel Quantum Nanodevice-Integrated Logic Circuits Utilizing BDD Architecture
Novel quantum-nanodevice-integrated logic circuits by the combination of binary decision diagram (BDD) logic architecture and semiconductor nanowire networks controlled by Schottky wrap gates (WPGs) are presented. Simple, small and flexible structure with fine gate control of the WPG
gives opportunity to implement a directed graph of a Boolean function on the nanowire network topologically. Quantum wire and single electron-type WPG-based node device are designed for BDD circuits and their operations are investigated experimentally. WPG BDD logic circuits from elemental
logic functions to subsystems using GaAs-based nanowire networks with hexagonal and 2D hypercube topologies are demonstrated. Feasibility of the WPG BDD circuits is confirmed by successful implementation of an ultra-small and ultra-low-power digital system, nanoprocessor, on a hexagonal network.
Device and circuit performances of the present approach are also discussed.
