Innovative plasmonic nanostructures as biosensor for DNA detection
Metallic nanoparticles and nanostructured surfaces show unique optical properties in the visible and NIR spectral range. Here, a plasmonic platform based on rhomb-shaped gold nanostructures is used to...
PublicationsUV fs-laser pulse durations from autocorrelation measurements in CaF2
For the determination of UV femtosecond laser pulse durations we use the autocorrelation technique based on two photon absorption (TPA) in CaF2 . To picture TPA of 197 nm laser radiation we measure either...
PublicationsPolymer solar cells blended with silicon nanowires
Solar cells based on conjugated polymers can be processed from solution or dispersion which offers a very important technological potential for low-cost fabrication using high-volume processes like reel...
PublicationsSandwich concept: Enhancement for direct absorption measurements by laser induced deflection (LID) technique
The new sandwich concept for absolute photo-thermal absorption measurements using the laser induced deflection (LID) technique is introduced and tested in comparison to the standard LID concept. The sandwich...
PublicationsFigures of merit of thermoelectric and bolometric thermal radiation sensors
Figures of merit condensing the performance parameters of radiation sensors such as responsivity, noise equivalent power and time constant in a single number can be useful for rating the performance of...
PublicationsReal-time mode analysis of fiber-to-fiber coupling processes using the correlation filter method
A frequent process in fiber optics is the fiber-to-fiber coupling where two fibers are aligned to efficiently transmit light from one to another waveguide. Such automated alignment processes are nowadays...
PublicationsAC losses in high pressure synthesized MgB2 bulk rings measured by a transformer method
Recently developed manufacturing technologies use high pressure and various doping additions to prepare bulk MgB2-based materials with a high critical current density measured by the magnetization method....
PublicationsPinning in MgB2- and YBaCuO-Based Superconductors: Effect of Manufacturing Pressure and Temperature
Bulk MgB2- and YBaCuO-based materials are competitive candidates for applications. The properties of both compounds can be significantly improved by high temperature-high pressure preparation methods....
PublicationsUncooled antenna-coupled terahertz detectors with 22μs response time based on BiSb/Sb thermocouples
We report on fast terahertz detectors based on antenna-coupled BiSb/Sb thermoelements operating at room temperature. A response time of the thermocouples as low as 22 μs and a NEP of 170 pW/sqrt(Hz) at...
PublicationsStructural Characterization of Insulin Fibril Surfaces using Tip Enhanced Raman Spectroscopy (TERS) NUR ABSTRACT
Amyloid fibrils are protein aggregates that are strongly associated with a variety of highly pathogenic diseases, such as Alzheimer’s disease, Creutzfeldt-Jakob disease, Parkinson disease, etc. Direct...
