SFQ Circuits with Ground Plane Hole-Assisted Inductive Coupling Designed with InductEx
The design of single flux-quantum (SFQ) circuits requires well-defined inductances. In many cases these are created by irregular geometries and a computer aided design tool is necessary for inductance...
PublicationsMathematical analysis of multiplexing techniques for SNSPD arrays
Superconducting single photon detectors (SNSPD) are distinguished by a very high sensitivity, a broad spectral range and a sparse dark count rate. Therefore, arrays of SNSPDs enable novel ultra sensitive...
PublicationsPlasmonic Coupling and Long-Range Transfer of an Excitation along a DNA Nanowire
We demonstrate an excitation transfer along a fluorescently labeled dsDNA nanowire over a length of several micrometers. Launching of the excitation is done by exciting the localized surface plasmon mode...
PublicationsModeling of noise-induced jitter in low-power mixed-signal circuits using a high-level description
This work describes the high-level modeling of the effects of noise for performance analyses in circuits and systems which are prone to statistical errors. In order to allow for comprehensive studies,...
PublicationsGeneration of volume Bragg gratings by 400 nm femtosecond laser pulses with Talbot-type interferometer in S-TIH53 glass
Volume Bragg gratings were inscribed in the non-photosensitive glass material S-TIH53 from OHARA using a fs laser system and a Talbot interferometer. We demonstrate the basic applicability of our technique...
PublicationsStable Scaffolds for Reacting Si Nanowires with Further Organic Functionalities while Preserving Si-C Passivation of Surface Sites
Functionalization of Si NWs with CH3sCHdCHs groups gives nearly full coverage of the Si atop sites. The resulting Si NWs provide high stability against oxidations and, at the same time, reactive functionality...
PublicationsNanopatterned Carbon Films with Engineered Morphology by Direct Carbonization of UV-Stabilized Block Copolymer Films
Nanopatterned thin carbon films were prepared by direct and expeditious carbonization of the block copolymer polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) without the necessity of slow heating to...
PublicationsSilicon nanowire-based solar cells
The fabrication of silicon nanowire-based solar cells on silicon wafers and on ulticrystalline silicon thin films on glass is described. The nanowires show a strong broadband optical absorption, which...
PublicationsFormation of nanovoids/microcracks in high dose hydrogen implanted AlN
Aluminium nitride (AlN) epitaxial layers grown on sapphire were implanted with 100 keV hydrogen, H2 + ions with doses in the range of 5 × 1016 cm–2 to 2.5 × 1017 cm-2 and subsequently annealed at temperatures...
PublicationsNanowires Enabling Signal-Enhanced Nanoscale Raman Spectroscopy
Silicon nanowires grown by the vapor–liquid–solid (VLS) mechanism catalyzed by gold show gold caps (droplets) approximately 20–500 nm in diameter with a half spherical towards almost spherical shape....
