Solid State Thermodynamics: • basics of thermodynamics, examples of importance of thermodynamics for materials science • metallurgical thermodynamics (thermodynamics and metal production) • thermodynamics of solutions (solid solutions - homogeneous alloys) • thermodynamics of phase equilibria Basics: How do you derive phase diagrams from thermodynamic principles? Discussion on Fe-C phase diagram. • thermodynamics of point defects • thermodynamics of surfaces and interfaces • thermodynamics of electrochemical reactions (application: fuel cells)
Electronic Materials: • semiconductor materials, elementary, binary, ternary and quaternary semiconductors, crystal structures • formation of band structures, direct and indirect semiconductors, bandgap, effective mass of carriers • carrier statistics, Fermi-distribution, density of states, carrier densities • intrinsic and doped semiconductors, carrier concentration and position of Fermi energy versus temperature, degenerate semiconductors • epitaxy of semiconductors, quantum wells and quantum dots, characterization of epitaxial layers • patterning of semiconductors, lithography, etching and material deposition • carrier transport, drude model, scattering processes, thermal and drift velocity, mobility, conductivity • diffusion, band structure in electric field • pn-junction, doping concentration, carrier densities, depletion region, electric field and potential • biased pn-junction, carrier transport and current-voltage characteristic

Lernziele und Kompetenzen:

The students apply principles of thermodynamics on relevant issues in materials science with the main focus on thermodynamics of alloys, including solid solutions and phase equilibria (phase diagrams).
The students: • understand the basic physical properties of semiconductors • review the fundamentals of semiconductor devices based on a discussion of the pn-junction diode • examine technological aspects such as growth and processing of semiconductors
