About the lecture

Time and place

Thursdays 1:00pm - 2:30 pm (s.t.), seminar room L204

In metals, light can couple to electrons to form a wave that is bound to the surface of the metal. This wave is called the surface plasmon. The surface plasmon mode is generally characterized by intense fields that decay exponentially away from the interface between the metal and the surrounding environment. Surface plasmons display very important properties, including strongly enhanced local fields; tremendous sensitivity to changes in the local environment; and the ability to localize energy to tiny volumes not restricted by the wavelength of the exciting light. Surface plasmons can also exist at the interface of metallic nanoparticles and their surrounding. In this case the wave is known as localized surface plasmon or particle plasmon. 


Due to their unique properties, plasmons have found a broad range of applications in various areas of science. In chemistry and biology for example, the sensitivity of surface plasmons is used to form the basis for powerful chemical and biochemical detectors that can monitor molecular binding events. In optics, the large field strengths of surface plasmons can dramatically enhance a variety of phenomena such as Raman scattering and light transmission through sub-wavelength apertures. In addition, the size of certain SPP configurations can be smaller than the operation wavelength, thus offering a path to decrease the size of optical components beyond the diffraction limit.

The seminar covers recent research highlights in plasmonics focusing on real applications including biosensing, laser-assisted manipulation, localized heating, cancer therapy and  many more. This seminar addresses in particular master students which have followed the lecture EM1 - Advanced Solid State Physics, but is not exclusively for these students.
