Enhanced Data-Processing Algorithms for Dispersive Interferometry Using a Femtosecond Laser

Sensors
Dispersive interferometry based on a femtosecond laser is extensively utilized for achieving absolute distance measurements with high accuracy. However, this method cannot measure arbitrary distances without encountering a dead zone, and deviations in ...

Real-Time Frequency Tracking of an Electro-Thermal Piezoresistive Cantilever Resonator with ZnO Nanorods for Chemical Sensing

Chemosensors, 2019
The asymmetric resonance response in electro-thermal piezoresistive cantilever resonators causes a need of an optimization treatment for taking parasitic actuation-sensing effects into account.

Time‐Resolved Cathodoluminescence Spectroscopy of Oxygen‐Related Defects in AlN Layers

physica status solidi (b), Volume 262, Issue 10, October 2025.
High‐temperature annealing significantly improves the crystal quality of sputter‐deposited AlN templates, but at the same time introduces oxygen‐related defects. Their origin is investigated using time‐resolved cathodoluminescence spectroscopy. Furthermore, these defects impact the deep‐UV transparency of the AlN templates.

Near-interface sensing, imaging and nanometrology using smart surfaces

EPJ Web of Conferences
We present two distinct types of ‘smart’ surfaces designed for facilitating the quantitative exploration of dynamic processes occurring at sub-wavelength distances from interfaces, using far-field optical techniques.

Multiscale Fabrication and Characterization of a NEMS Force Sensor

Advanced Materials Technologies, Volume 10, Issue 4, February 19, 2025.
Fabricated silicon nanowires integrated with MEMS shuttle on a silicon‐on‐insulator wafer using novel fabrication technology enable the device to detect subtle multi‐axis forces. Gage factor tests show static manipulation response, while dynamic analysis indicates robustness and high resonant frequency.

Surface‐Enhanced Raman Scattering and Photothermal Effects on Optoplasmonic Nanofibers

Advanced Optical Materials, Volume 12, Issue 34, December 3, 2024.
Plasmonic nanofibers made of pulled glass fibers decorated with metallic nanoparticles exhibit unique optical properties owing to the interactions between the incident light with both the optical modes of the nanofiber and the localized surface plasmon resonance of the nanoparticles.

Quantum criticality in the coupled two-leg spin ladder Ba2CuTeO6

, 2017
We report on zero-field muon spin rotation, electron spin resonance and polarized Raman scattering measurements of the coupled quantum spin ladder Ba2CuTeO6. Zero-field muon spin rotation and electron spin resonance probes disclose a successive crossover
