Nanocell Devices and Architecture for Configurable Computing With Molecular Electronics
Artikel i vetenskaplig tidskrift, 2007
We develop a method to configure a 3-D nonlinear
nanoparticle-molecule network to performing ten out of twelve
possible combinations of two 2-bit logic gates with shared inputs.
The logic gates are based on a simple circuit with adjustable
linear and fixed negative differential resistance (NDR) elements.
A bistable latch for signal restoration is an integral part of this
target circuit. The simulations show that conductive patterns
can be formed by applying voltages on the input–output pins
of the nanocell. They also show that one-link gaps (short highly
resistive links) can be created within the conductive channels.
Furthermore, we discuss methods for introducing NDR molecules
in these gaps, a crucial element of the target circuit. The structures
resulting from the simulations are put in an architectural context,
in which complex functions can be realized from the individual
nanocell logic gates.
