Correlating internal stresses, electrical activity and defect structure on the micrometer scale in EFG silicon ribbons
In the present paper, we study the influence of defects through their stress fields on the electrical activity and residual stress states of as-grown edge-defined film-feed (EFG) multicrystalline silicon...
PublicationsCatalyst-free functionalization for versatile modification of nonoxidized silicon structures
Here, we report on a simple, catalyst-free route for obtaining highly versatile subsequent functionalization on Si nanowires and Si(111) substrates. The versatility of this approach allows subsequent functionalization...
PublicationsChemical and Optical Characterisation of Atomic Layer Deposition Aluminium doped ZnO films for Photovoltaics by Glow Discharge Optical Emission Spectrometry
Aluminium doped ZnO (AZO) alloy films produced by atomic layer deposition (ALD) are analysed by glow discharge optical emission spectrometry (GD-OES). A measurement procedure is established, to determine...
PublicationsProtonation effects on the resonance Raman properties of a novel (terpyridine)Ru(4H-imidazole) complex: An experimental and theoretical case study
The optically active states in a novel Ruthenium-terpyridine complex displaying an unusually broad and redshifted absorption in the visible range are investigated experimentally and theoretically. While...
PublicationsGrowth of doped silicon nanowires by pulsed laser deposition and their analysis by electron beam induced current imaging
Doped silicon nanowires (NWs) were epitaxially grown on silicon substrates by pulsed laser deposition following a vapour–liquid–solid process, in which dopants together with silicon atoms were introduced...
PublicationsPhotoluminescence of samples produced by Electroless Wet Chemical Etching: Between silicon nanowires and porous structure
Samples containing silicon nanowires (Si-NWs) and highly porous structures (P-Si) were prepared by ElectrolessWet Chemical Etching (EWCE) of crystalline silicon wafers using various etching parameters....
PublicationsMagnetic multicore nanoparticles for hyperthermia – influence of particle immobilisation in tumour tissue on magnetic properties
When using magnetic nanoparticles as heating source for magnetic particle hyperthermia it is of particular interest to know if the particles are free to move in the interstitial fluid or fixed to the tumour...
PublicationsInvestigations on magnetic particles prepared by cyclic growth
Magnetic iron oxide nanoparticles are promising tools for medical applications like hyperthermia or magnetic drug targeting. The relevant properties in these applications strongly depend on particle size...
PublicationsReinvestigation of the M Emission Spectrum of Uranium-92
The M spectrum of the element uranium was reinvestigated by using both high-resolution wavelength dispersive (WD) spectrometry as well as energy dispersive (ED) pectrometry. Thereby we observed relative...
PublicationsGrowth of axial SiGe heterojunctions in nanowires using PLD
Axial heterojunctions between pure silicon and pure germanium in nanowires have been realized combining pulsed laser deposition, chemical vapor deposition and electron beam evaporation in a vapor-liquid-solid...
