Design analysis and optimization of a polarity gate controlled Schottky barrier CNT FET model

Abstract

The proposed research focuses on the development of a systematic design method that optimizes circuit speed and power consumption specifically for Carbon Nanotube Field Effect Transistor (CNFET) technology. The optimization methods proposed in this thesis differ from those employed in traditional CMOS circuit design, as they consider the unique characteristics of CNFETs and the associated circuitry. newlineThe development of proposed CNTFET model using ant lion optimization (ALO) technique is an intriguing approach to explore device physics and enhance simulation capabilities. ALO is a nature-inspired metaheuristic algorithm that mimics the behaviour of ant lions, insects known for their unique hunting strategy. The algorithm is based on the concept of capturing prey by creating traps in the form of conical pits. In the context of CNTFET modelling, the ant lion optimization technique is utilized to develop an effective and accurate model. This model aims to capture the intricate physics and behaviour of CNTFETs, considering factors such as carrier transport, electrostatics, and device characteristics. newline newline
