Boosting light collecting efficiency of optical fibers via metallic nano-structures
Optical fibers represent one of the most important photonic components with applications in numerous fields while their performance with respect to light collection at large incident angle is strongly...
PublikationenField-Driven Hopping Transport of Oxygen Vacancies in Memristive Oxide Switches with Interface-Mediated Resistive Switching
We investigate the hopping transport of positively charged mobile oxygen vacancies V+o in electroforming-free bipolar memristive BiFeO3 switches by conducting impedance spectroscopy and quasistatic state-test...
PublikationenPowering an autonomous sensor by silicon nanowire solar cells – the SiNAPS mote
In order to power miniaturized sensor modules, a miniaturized solar module was developed within the SiNAPS project. The silicon nanowire based solar cell shows an OC voltage of 517 mV. We also present...
PublikationenA Time-Resolved Numerical Study of the Vapor−Liquid−Solid Growth Kinetics Describing the Initial Nucleation Phase as well as Pulsed Deposition Processes
Today, the Vapor-Liquid-Solid growth mechanism is a common process for the bottom-up growth of nanowires (NWs). Nevertheless, most of the literature only concerns the steady-state growth which applies...
PublikationenDispersion analysis of the orthorhombic peptide single crystal Z-(Aib)3-L-Ala-OtBu
We present a dispersion analysisof the orthorhombic peptide single crystal Z-Aib-Aib-AibL-Ala-OtBu (N-benzyloxycarbonyl-α-aminoisobutyryl-α-aminoisobutyryl-L-alanine tertbutyl ester, C27H42N4O7), where...
PublikationenBeer’s law – why absorbance depends (almost) linearly on concentration
Beer’s law assumes a strictly linear dependence of the absorbance from concentration. Usually, chemical interactions and instrumental imperfection are made responsible for experimental deviations from...
PublikationenSupporting Information: Controlling Intermolecular Interactions at Interfaces: Case of Supramolecular Tuning of Fullerene’s Electronic Structure
It is demonstrated that systematic and designated control of supramolecular nanostructures via interfacial engineering enables (opto)electronic C60-material properties to be widely adjusted. Interestingly,...
PublikationenDetection of the anomalous velocity and anomalous Hall effect in GaAs via free-space THz spectroscopy
The anomalous velocity causes spin-polarized carriers to move perpendicular to an electric or parallel to a magnetic driving field. It is at the origin of the spin Hall and anomalous Hall effects. Here,...
PublikationenControlling Intermolecular Interactions at Interfaces: Case of Supramolecular Tuning of Fullerene’s Electronic Structure
It is demonstrated that systematic and designated control of supramolecular nanostructures via interfacial engineering enables (opto)electronic C60-materialproperties to be widely adjusted. Interestingly,...
PublikationenComparison of time-domain SH waveform inversion strategies based on sequential low and bandpass filtered data for improved resolution in near-surface prospecting
The full waveform inversion (FWI) of strongly dispersive Love wave data is a challenging task. Amplitude, phase and dispersion information not only depends on the density and shear modulus distribution...
