TCAD is a component that will help you write vector graphics applications. Shapes can be interacted with by mouse or code. It is easy to use, effective and powerful.
I will then supply you with the necessary files and give you a live tutorial on how to inspect TCAD simulation outputs. To keep it manageable, we will focus on using existing codes provided so that you can use TCAD to understand devices without having to spend a lot of time putting together working TCAD input decks or coding.
