Replacing incandescent lamps by solid-state lighting is expected to yield significant energy savings in the future. We discuss the physical principles of high brightness light emitting diodes (LEDs), the properties of nitride semiconductors used for LED fabrication, and the deposition, patterning and packaging techniques required for white LED production for general lighting purposes.
This course will cover the basic topics in Physics and will show/display/explain with a variety of experiments the most important physical effects. The course will address classical as well as modern physics, and the interplay between basic research and applications.
Scanning Probe Techniques
Rastersensor-Methoden
The theoretical foundations of scanning tunneling microscopy and spectroscopy and their application to semiconducting and metallic surfaces are treated, as well as the relation between atomic forces and the tunnel effect, and the scanning force microscope. Ballistic electron emission microscopy is shown to provide an extension of the scanning tunneling microscope to the study of buried interfaces.
