Physics and Chemistry of Functional Interfaces

The newest developments in microelectronics, energy conversion, and sensing device design are tied very closely to our ability to develop new hybrid systems where molecular and electronic control of the structure is key. The optimization of interfaces in different inorganic-organic device systems depends strongly on our level of control and understanding of both the molecular chemical processes involved on surfaces and the effects on the electronic states. The lecture is devoted to achieve a fundamental understanding of the physical, chemical, biological, structural, and electrical properties of these complex heterostructures. In particular the lecture will focus on the structure of crystalline solids and surface lattices, origins of surface reactivity and growth processes, interfacial phenomena and change of energy levels in heterostructure optimization, and on the formation of organic nanostructures and bioorganic films. Moreover current highlights in the literature on the application of functional interface on semiconductor devices will be discussed. In addition a short overview of the mostly applied characterization tools and novel surface imaging and spectroscopy techniques applied in the field will be given.

After participation in the module the student will be able 1. understand how electrical and chemical properties can be modulated in functional interfaces, 2. understand different areas of application of surface functionalization, 3. evaluate the importance of heterostructure formation in device optimization, 3. understand the basics of the most common used characterization techniques in the field.

Curiosity and openness for interdisciplinary fields.
