Course Description This course introduces the fundamental semiconductor physics underlying modern energy-conversion technologies. Students will learn how quantum mechanics, electronic band structures, density of states (DOS), carrier statistics, and charge transport govern the behavior of semiconductor materials. The course emphasizes the analysis of metal–semiconductor contacts, p–n junctions, heterojunctions, and semiconductor–electrolyte interfaces, and their roles in determining charge separation and transfer in solar cells, photoelectrochemical water-splitting systems, and related energy applications. Objectives By the end of this course, students will be able to: • Explain the fundamental concepts of quantum mechanics, electronic band structures, and density of states in semiconductor materials. • Analyze carrier distributions, Fermi levels, and charge transport processes in intrinsic and doped semiconductors. • Interpret and construct energy-band diagrams for metals, semiconductors, metal–semiconductor contacts, p–n junctions, and heterojunctions. • Evaluate charge separation, carrier transport, and recombination mechanisms using band alignment and density-of-states analysis. • Analyze the effects of junction design and interfacial electronic structure on device performance. • Apply thermodynamic and kinetic principles to charge-transfer processes in semiconductor-based energy systems. • Assess semiconductor materials and interfaces for applications in photovoltaic devices, photoelectrochemical water splitting, photocatalysis, and related renewable-energy technologies.
This course is open to all graduate students with a background in science or engineering. Familiarity with basic concepts in chemistry, physics, or materials science is expected.
