Introduction to nextnano: Simulation and Analysis

This lecture introduces the nextnano simulation software, focusing on the input file structure and the simulation process. It covers topics such as the Poisson Equation, Drift-Diffusion Equation, and Schrödinger Equation used in the simulation. The lecture also explains the process of determining charge density distribution, solving the Poisson equation self-consistently, and analyzing the potential within the device. Additionally, it delves into the use of materials, variables, and quantum regions in the simulation, providing insights into running multiple simulations automatically and visualizing the output. The lecture concludes with a discussion on the breakdown of a typical nextnano input file and practical tips for efficient simulation and analysis.
