Semiconductor Materials and Nanostructures

This lecture covers the history of semiconductor materials and nanotechnology, the structure and appearance of energy gaps, band structure, density of states in nanostructures, charge carriers in semiconductors, doping, Fermi level, electronic transport, optical properties, and applications. It also includes seminars on various topics related to semiconductor nanowires, graphene, high electron mobility transistors, tunnel transistors, photonic concepts, TMD-based devices, and single photon emitters. The course emphasizes the chemical bond, energy gap, top-down vs bottom-up approaches, band structure, effective mass, mobility, optical properties, new semiconductors like oxides and 2D materials, and practical examples of semiconductors in daily life.
