MATLAB-Based Simulation Program for Nanoscale Carbon Nanotube Transistors

We can develop a MATLAB-based simulation program for nanoscale carbon nanotube transistors, which serves as a powerful tool for designing and evaluating next-generation nanoscale transistor devices. This simulation program models the performance characteristics of carbon nanotube transistors, including current transport mechanisms and electron mobility dynamics. The implementation typically involves solving quantum transport equations using MATLAB's numerical computation capabilities, such as employing the Non-Equilibrium Green's Function (NEGF) method coupled with Poisson's equation solvers. Within the simulation environment, users can adjust various parameters including tube length and diameter, material properties, gate voltages, and temperature conditions to gain deeper insights into the operational principles of carbon nanotube transistors. The code architecture may include modular functions for parameter initialization, Hamiltonian matrix construction, and current-voltage characteristic calculation. Additionally, the program enables exploration of different design configurations through parameter sweeping algorithms and optimization routines to identify optimal performance characteristics. This simulation platform provides valuable understanding of nanoscale transistor design and performance metrics, serving as a crucial reference framework for future electronic device development. The MATLAB implementation typically utilizes built-in functions for matrix operations and differential equation solving, while incorporating visualization tools for plotting transfer characteristics, output curves, and band structure diagrams.
