Physical Electronics (EEE325) examines the physics of silicon-based microelectronic semiconductor devices. Topics covered are: Energy bands and charge carriers in semiconductors, excess carriers in semiconductors, pn junctions, and metal-oxide semiconductor field-effect transistors (MOSFETs). The course emphasizes physical models for semiconductor electronic devices and understanding of device operation through energy band diagrams. The application of these models to the analysis and design of the devices are also outlined.
