Sentaurus TCAD Modeling and Simulation

This repository provides example simulation files and learning materials for semiconductor device modeling using Synopsys Sentaurus TCAD. It is designed for beginners and intermediate users who want a practical workflow from structure creation to results visualization.

Tools used: SEditor (structure) -> Doping -> Meshing -> SDevice (simulation) -> SVisual (results)

What's Inside

• Step-by-step workflow: SEditor -> Doping -> Meshing -> SDevice -> SVisual.
• Example simulation: 2D MOS transistor (basic).
• Input files to tweak and extend for your own devices.
• Links to learning resources for deeper study.

---

Prerequisites

• Access to Synopsys Sentaurus TCAD (licensed).
• Basic familiarity with semiconductor device physics (Poisson + continuity, drift-diffusion).

---

Getting Started

1. Clone this repository:

git clone https://github.com/rayid-mojumder/Sentaurus-TCAD-Modeling-and-Simulation.git

2. Open the project in Sentaurus Workbench (or run individual tools).
3. Follow the order inside Simulation_Files/:
   • Build geometry in SEditor
   • Define Doping
   • Create Meshing
   • Run device simulation in SDevice
   • Visualize in SVisual
4. Plot key results (ID–VG, ID–VD, band diagram, carrier densities).
