Tino Hofmann received the best poster award at the ICSE 4 for his presentation of the "Optical-Hall
Effect". His poster summarized his recent developments of the optical-Hall effect.
Applications range from 3D electron gases in multilayer semiconductor systems to the observation of the optical Quantum Hall
effect in highly oriented pyrolytic graphite at low temperatures. In essence, the optical Hall effect addresses the optical birefringence in the THz and
infrared spectroscopic domains and is caused by the interaction of the electromagnetic radiation with bound and unbound electrical charge carriers subjected
to an external magnetic. The generalized ellipsometry technique is the backbone of the Optical Hall effect, and was invented and developed at UNL.
