Microstructure of Silicon Nanorods for Novel Solar Cells
Silicon nanorods were produced by the vapor-liquid-solid process and by wet chemical etching as possible candidates for solar cells. The nanostructures of Si nanorods formed by the two different processes...
PublicationsLinear and Non-Linear Optical Imaging of Cancer Cells with Silicon Nanoparticles
New approaches for visualisation of silicon nanoparticles (SiNPs) in cancer cells are realisedby means of the linear and nonlinear optics in vitro. Aqueous colloidal solutions of SiNPs with sizesof about...
PublicationsEffect of Ion Beam Figuring and Subsequent AR Coating Deposition on the Surface Absorption of CaF2 at 193nm
Laser induced deflection (LID) technique is used to investigate the CaF2 surface absorption at 193nm after surface treatment by ion beam figuring (IBF) and subsequent AR coating process, respectively....
PublicationsSynthesis of three series of ruthenium tris-diimine complexes containing acridine-based π-extended ligands using an efficient “chemistry on the complex” approach
The preparation and characterization of three series of novel ruthenium (II) complexes are reported, each series differing by the nature of the ancillary ligands (2,2’-bipyridine – bpy, 1,10-phenanthroline...
PublicationsOptimization of the Microwave Properties of the Kinetic-Inductance Bolometer (KIBO)
Silicon nitride membrane based cryogenic bolo-meters exhibit high sensitivity and enable ultra-sensitive detector applications. Multi-pixel instruments were already introduced as devices for submillimeter-wave...
PublicationsPhotoluminescence at room temperature of liquid-phase crystallized silicon on glass
The room temperature photoluminescence (PL) spectrum due band-to-band recombination in an only 8 um thick liquid-phase crystallized silicon on glass solar cell absorber is measured over 3 orders of magnitude...
PublicationsCovalent Photosensitizer–Polyoxometalate-Catalyst Dyads for Visible-Light-Driven Hydrogen Evolution
A general concept for the covalent linkage of coordination compounds to bipyridine-functionalized polyoxometalates is presented. The new route is used to link an iridium photosensitizer to an Anderson-type...
PublicationsMultijunction a-Si:H/c-Si solar cells with vertically-aligned architecture based on silicon nanowires
The new design for full silicon multi-junction solar cells, which consists of combination of silicon nanowires (SiNWs) and conventional silicon-based hetero-junctions, is proposed in the paper. A top junction...
PublicationsAbsolute calibration of a three-axis SQUID-cascade vector magnetometer
We report on the absolute calibration of a three-axis SQUID-cascade vector magnetometer suited for mobile operation in the Earth’s magnetic field. It is based on LTS dc SQUIDs with sub-micrometer sized...
PublicationsAntimicrobial effect of biocompatible silicon nanoparticles activated by therapeutic ultrasound
In this study, we report a novel method of suppression of Escherichia coli (E.coli) culture vitality using biocompatible silicon nanoparticles as sensitizers of cavitation processes of therapeutic ultrasound...
