Conducted for the ECE 515: Fundamentals of Semiconductor Devices course at Portland State University, this project uses Excel for data analysis, offering insights into diode behavior through graphical analysis and theoretical model comparisons.\n\n## Data Analysis\nExcel was chosen for its interactivity and simplicity in handling the project's data analysis requirements. The analysis involves:\n- Plotting linear and semi-logarithmic I-V characteristics.\n- Fitting the data to the diode equation to extract parameters like the ideality factor and saturation current.\n- Assessing the impact of temperature on diode performance.\n- Comparing experimental data with theoretical predictions.\n\n## Repository Structure\n- **Collected Data/**: Contains raw data files used in the analysis.\n- **Analysis Sheets/**: Excel files with plotted graphs and fitted models.\n- **Report/**: Detailed project report including methodology, results, and conclusions.\n- **README.md**: Provides an overview of the project and instructions for navigating the repository.\n\n## Results Overview\nThe project successfully demonstrates the temperature dependence of the diode's I-V characteristics, revealing significant insights into the diode's operational behavior. Key findings include the extraction of the diode's ideality factor and saturation current, and the observation of shifts in the I-V curve with temperature changes.\n\n## Contributing\nContributions to improve the analysis or extend the study are welcome. Please fork the repository, make your changes, and submit a pull request.\n\n## Credits\n- **Mohamed Ghonim**: Project lead and author of the analysis.\n- **Prof. Malgorzata Chrzanowska-Jeske**: Supervisor and course instructor.\n\n## License\nThis project is shared under the MIT License.
