Kurzbeschreibung	The lecture deals with thermodynamics and transport phenomena in nano- and microscale systems. Typical areas of applications are microelectronics manufacturing and cooling, manufacturing of novel materials and coatings, surface technologies, wetting phenomena and related technologies, and micro- and nanosystems and devices.
Lernziel	The student will acquire fundamental knowledge of interfacial and micro-nanoscale thermofluidics including electric field and light interaction with surfaces. Furthermore, the student will be exposed to a host of applications ranging from superhydrophobic surfaces and microelectronics cooling to solar energy, all of which will be discussed in the context of the course. The student will also judge state-of-the-art scientific research in these areas.
Inhalt	Thermodynamic aspects of intermolecular forces; Interfacial phenomena; Surface tension; Wettability and contact angle; Wettability of Micro/Nanoscale textured surfaces: superhydrophobicity and superhydrophilicity. Physics of micro- and nanofluidics as well as heat and mass transport phenomena at the nanoscale. Scientific communication and exposure to state-of-the-art scientific research in the areas of Nanotechnology and the Water-Energy Nexus.

402-0596-00L	Electronic Transport in Nanostructures	W	6 KP	2V + 1U	T. M. Ihn
Kurzbeschreibung	The lecture discusses modern topics in quantum transport through nanostructures including the underlying materials. Topics are: the quantum Hall effects with emphasis on the fractional quantum Hall effect, two-dimensional topological insulators, graphene and other 2D layered materials, quantum interferometers, quantum dot qubits for quantum information processing, decoherence of quantum states
Lernziel	Students are able to understand modern experiments in the field of electronic transport in nanostructures. They can critically reflect published research in this field and explain it to an audience of physicists. Students know and understand the fundamental phenomena of electron transport in the quantum regime and their significance. They are able to apply their knowledge to practical experiments in a modern research lab.
Skript	The lecture is based on the book: T. Ihn, Semiconductor Nanostructures: Quantum States and Electronic Transport, ISBN 978-0-19-953442-5, Oxford University Press, 2010.
Voraussetzungen / Besonderes	A solid basis in quantum mechanics, electrostatics, quantum statistics and in solid state physics is required. Having passed the lecture Semiconductor Nanostructures (fall semester) may be advantageous, but is not required. Students of the Master in Micro- and Nanosystems should at least have attended the lecture by David Norris, Introduction to quantum mechanics for engineers. They should also have passed the exam of the lecture Semiconductor Nanostructures.
