With the successful course attendance the students are able to interprate material behavior related to mass or charge transport (i.e. diffusion, electrical properties) and to design the detailed crystal structure of a material, including the type and concentration of dominating point defects, towards a desired material behavior
Course Content (Syllabus)
Intrinsic and extrinsic point defects in oxides. Ionic point defect diagrams. Electronic defects. Intrinsic non stoichiometry. Extrinsic non stoichiometry. Brouwer diagrams for point defects. Applications in temperature sensors (possitive or negative coefficient), ionic conductors in fuel cells, gas sensors, humidity sensors, ohmic resistors, thermal elements, magnetic materials.
point defects, defect chemistry, Brouwer diagrams, electronic ceramic materials
