Current-induced nanogap formation and graphitization in boron-doped diamond films
V. Seshan, C. R. Arroyo, A. Castellanos-Gomez +9
A high-current annealing technique is used to fabricate nanogaps and hybrid diamond/graphite structures in boron-doped nanocrystalline diamond films. Nanometer-sized gaps down to 1…
Tuning the Fano resonance between localized and propagating surface plasmon resonances for refractive index sensing applications
Kristof Lodewijks, Jef Ryken, Willem Van Roy +3
Localized and propagating surface plasmon resonances are known to show very pronounced interactions if they are simultaneously excited in the same nanostructure. Here we study the…
Bridging the Mid-Infrared-to-Telecom Gap with Silicon Nanophotonic Spectral Translation
Xiaoping Liu, Bart Kuyken, Gunther Roelkens +3
Expanding far beyond traditional applications in optical interconnects at telecommunications wavelengths, the silicon nanophotonic integrated circuit platform has recently proven i…
Influence of the pattern shape on the photonic efficiency of front-side periodically patterned ultrathin crystalline silicon solar cells
Aline Herman, Christos Trompoukis, Valerie Depauw +2
Patterning the front side of an ultra-thin crystalline silicon (c Si) solar cell helps keeping the energy conversion efficiency high by compensating for the light absorption losses…
Wigner distribution functions for complex dynamical systems: a path integral approach
Dries Sels, Fons Brosens, Wim Magnus
Starting from Feynman's Lagrangian description of quantum mechanics, we propose a method to construct explicitly the propagator for the Wigner distribution function of a single sys…
Method for Flow Measurement in Microfluidic Channels Based on Electrical Impedance Spectroscopy
Nima Arjmandi, Chengxun Liu, Willem Van Roy +2
We have developed and characterized two novel micro flow sensors based on measuring the electrical impedance of the interface between the flowing liquid and metallic electrodes emb…
