IEEE 32- Multi-path Switching Device Utilizing A Multi-terminal Nanowire Junction for MDD-based Logic Circuit


Simple and compact multi-path switching devices
for multi-valued decision diagram (MDD)-based logic
circuits are designed, fabricated and characterized.
The devices switch multiple exit branches for electrons
entering from an entry branch, according to multivalued
input. The switching function is implemented
by dual gating on multiple nanowires with different
threshold voltages. The gate threshold voltage is
controlled by precise design of gate structures and
sizes in nanometer scale. The operation principle of
the device is described using a simple analytical model.
Ternary-path switching devices are demonstrated
using AlGaAs/GaAs etched nanowire junctions
together with nanometer-scale Schottky wrap gates
(WPGs) and in-plane gates (IPGs).
