Semester Project and Lab Assignments for the Structure and Electrical Properties of Materials course, during the 2nd semester of the School of Electrical and Computer Engineering at the National Technical University of Athens.
The semester project aimed at giving a practical insight on the electrical properties of materials. The project was divided into five problems, that covered the topics that follow.
- Energy Gaps in Semiconductors
- Fermi-Dirac Distribution
- Electron and Hole Density in Semiconductors
- Law of Mass Action
- Electron Density in Impure Semiconductors
To solve some of the problems, MATLAB was used, to simulate scenarios and produce graphs.
There were 2 lab assignments in total. The first one was an introduction to the lab equipment and had a few basic questions and experiments, including measuring resistances, using a multimeter and using the oscilloscope to calculate frequencies. The second one was more advanced and included diodes, capacitors, RC circuits, Half-Wave and Full-Wave Rectifiers, Signal Smoothing and Peak Detection.
