Multiple Path Switching Device Utilizing Size-Controlled Nano-Schottky Wrap Gates for MDD-Based Logic Circuits

A novel simple and compact multiple-path-switching device for multiple-valued decision diagram (MDD) is proposed and investigated theoretically in order to realize highperformance nanowire-network-based logic circuits with advanced functionality. The device is designed on multi-semiconductor-nanowire branches having a couple of size-controlled nanometer-scale Schottky wrap gates (WPGs). The device selects an exit branch for messenger electrons according to gate voltage as a multiple-valued input variable. The pathswitching function is realized by multiple assign of gate threshold voltages and applying complementary gate voltages to the two WPGs. Theoretical investigation based on threedimensional potential simulation confirms that clear current path switching takes place in the proposed device.
