Field-Effect Transistors based on Silicon Nanowire Arrays: Effect of the Good and the Bad Silicon Nanowires
Aligned arrays of silicon nanowires (aa-Si NWs) allow to exploit their nanoscale properties in a scalable way. Previous studies explored the influence of the number, doping density, and diameter of the...
PublikationenWet chemically prepared silicon nanowire arrays on low-cost substrates for photovoltaic applications
Silicon nanowire (SiNW) based solar cells are a promising candidate for third generation solar cells with high effi¬ciency, which will further reduce the cost of the PV modules, making it competitive...
PublikationenTemperature dependent optical properties of amorphous silicon for diode laser crystallization
The temperature dependent optical parameters n and k of amorphous silicon deposited by electron beam evaporation were determined at the wavelength of 808 nm. This was achieved by fitting an optical model...
PublikationenGrowth, Structure and Optical Properties of Silicon Nanowires Formed by Metal-Assisted Chemical Etching
Silicon nanowires (SiNWs) formed by metal(silver)-assisted chemical etching of lowly boron-doped (100)-oriented single crystalline silicon substrates in hydrofluoric acid solutions are investigated by...
PublikationenDynamic behavior of dc SQUIDs in time-division multiplexing readout schemes
We have investigated the transient response of superconducting quantum interference devices (SQUIDs) used in time-division multiplexing schemes for the readout of arrays of superconducting transition-edge...
PublikationenMonitoring the morphochemistry of laryngeal carcinoma by multimodal imaging
Multimodal nonlinear imaging constitutes a contemporary approach to investigate the morphochemistry of complex samples noninvasively and without administration of external labels. Here we discuss our recent...
PublikationenCharacterization and Application of Innovative Plasmonic Arrays
In order to increase the inherent weak but molecular specific Raman signature the exceptional optical properties of plasmonic nanostructures are used. This technique is termed as surface enhanced Raman...
PublikationenSplitting and switching of microfluid segments in closed channels for chemical operations in the segment-on-demand technology
Basic functional units and a preparation technology have been developed for the investigation of segment operations in larger sequences of droplets. A high reproducibility of segment operations with branched...
PublikationenNoise characterization of highly sensitive SQUID magnetometer systems in unshielded environments
To measure the noise performance of highly sensitive SQUID magnetometers is nearly impossible due to superimposed external noise. Especially in unshielded environment one needs sophisticated methods in...
PublikationenNon-invasive label-free investigation and typing of head and neck cancers by multimodal nonlinear microscopy
Early detection and typing of tumors is pressing matter in clinical research with important impacts for prognosis and successful treatment. Currently, staining is the golden standard in histopathology...
