1. Light polarization in single molecule spectroscopy: From visualization of structural anisotropy and energy transfer to super-resolution imaging with orientational contrast
Sammanfattning : Π-conjugated polymers are an important class of materials which can be used in e.g. photoelectric (solar cells) or electroluminescent (displays) devices. These materials are implemented in a number of applications these days since a lot is already known about them. LÄS MER
2. The Fate of Electronically Excited States : Ultrafast Electron and Energy Transfer in Solvated Donor-Acceptor Systems
Sammanfattning : Processes where a molecule absorbs visible light and then disposes of the excess energy via electron/energy transfer reactions have an important role both in nature (e.g. in photosynthesis) and in many technical applications (e.g. LÄS MER
3. Photospheric emission from structured, relativistic jets : applications to gamma-ray burst spectra and polarization
Sammanfattning : The radiative mechanism responsible for the prompt gamma-ray burst (GRB) emission remains elusive. For the last decade, optically thin synchrotron emission from shocks internal to the GRB jet appeared to be the most plausible explanation. LÄS MER
4. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging
Sammanfattning : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

5. Diamond Devices Based on Valley Polarization
Sammanfattning : Diamond is a wide bandgap semiconductor with extreme properties such as high thermal conductivity, high breakdown field, high carrier mobilities and chemical inertness. These properties together with the possibility to synthesize high purity Single-Crystalline (SC) diamond by Chemical Vapor Deposition (CVD), make it a very interesting material and a candidate for use in power electronics and in hazardous environments.
