KurzbeschreibungThe lecture deals with both: the thermodynamics in nano- and microscale systems and the thermodynamics of ultra-fast phenomena. Typical areas of applications are microelectronics manufacturing and cooling, laser technology, manufacturing of novel materials and coatings, surface technologies, wetting phenomena and related technologies, and micro- and nanosystems and devices.
LernzielThe student will acquire fundamental knowledge of micro and nanoscale interfacial thermofluidics including light interaction with surfaces. Furthermore, the student will be exposed to a host of applications ranging from superhydrophobic surfaces and microelectronics cooling to biofluidics and solar energy, all of which will be discussed in the context of the course.
InhaltThermodynamic aspects of intermolecular forces, Molecular dynamics; Interfacial phenomena; Surface tension; Wettability and contact angle; Wettability of Micro/Nanoscale textured surfaces: superhydrophobicity and superhydrophilicity.

Physics of micro- and nanofluidics.

KurzbeschreibungThe lecture describes various nanomaterials (semiconductor, metal, dielectric, carbon-based...) for photonic applications (optoelectronics, plasmonics, photonic crystal...). It starts with nanophotonic concepts of light-matter interactions, then the fabrication methods, the optical characterization techniques, the description of the properties and the state-of-the-art applications.
LernzielThe students will acquire theoretical and experimental knowledge in the different types of nanomaterials (semiconductors, metals, dielectric, carbon-based, ...) and their uses as building blocks for advanced applications in photonics (optoelectronics, plasmonics, photonic crystal, ...). Together with the exercises, the students will learn (1) to read, summarize and discuss scientific articles related to the lecture, (2) to estimate order of magnitudes with calculations using the theory seen during the lecture, (3) to prepare a short oral presentation about one topic related to the lecture, and (4) to imagine a useful photonic device.
