Design and analysis of QCA adder circuits for efficient computation
ITEGAM-JETIA, 2021 QCA technology is considered a viable alternative for CMOS technology since it solves most of the CMOS implications. The Quantum dot Cellular Automata is a computer software program that relates a discrete dynamical system with quantum mechanics. Quantum

Sequential circuit design in quantum-dot cellular automata [PDF]
, 2008 In this work we present a novel probabilistic modeling scheme for sequential circuit design in quantum-dot cellular automata(QCA) technology. Clocked QCA circuits possess an inherent direction for flow of information which can be effectively modeled ...

Modeling magnetic quantum-dot cellular automata by HDL [PDF]
2011 11th IEEE International Conference on Nanotechnology, 2011 Quantum-dot Cellular Automata (QCA) is one of the emerging technologies that have been advocated to overcome the physical limitations of CMOS in the nano ranges. For QCA to be a viable alternative to CMOS in the decades ahead, tools and methodologies at physical and logic levels are urgently needed in support of all design phases.

Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures
Advanced Functional Materials, EarlyView.The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

Near Zero-Energy Computation Using Quantum-dot Cellular Automata
, 2019 Near zero-energy computing describes the concept of executing logic operations below the (kBT ln 2) energy limit. Landauer discussed that it is impossible to break this limit as long as the computations are performed in the conventional, non-reversible ...

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
