Lernziele

Upon successful completion of the module, students understand the principles of interfacial band engineering central to modern micro– and nanoelectronics. They are able to construct and analyze band diagrams across a wide range of material systems and interfaces, and relate band alignment to the operation of fundamental electronic building blocks. Students can apply these concepts to diverse thin–film and 2D semiconductor heterostructures, gaining insight into interface functionality and pathways for device optimization.
