Antibiotic‐Mediated Plasmonic‐Mie Resonance for Biosensing Applications on a Novel Silicon Nanopillar Metasurface

Advanced Materials Interfaces, EarlyView.
Unique nanopillar metasurfaces are fabricated for the purpose of sensitive detection to refractive index changes in the presence of gold nanoparticles. The addition of these nanoparticles to the surface of the silicon nanopillars is facilitated via a novel antibiotic‐mediated linker system to promote localized surface plasmon effects resulting from Mie

Wafer‐Scale Synthesis of Topological Insulator Sb2Te3 Thin Films

Advanced Materials Interfaces, EarlyView.
This work demonstrates how the topologically protected conduction in Sb2Te3 thin films can be extended from few‐mm2 samples’ area up to larger areas of several cm2 Si(111) wafers. The reported findings represent a breakthrough for the future technology scale‐up of topological insulators for applications such as spintronics, thermoelectrics, and quantum

Silicon photonics beyond silicon-on-insulator [PDF]

Journal of Optics, 2017
The standard platform for silicon photonics has been ridge or channel waveguides fabricated on silicon-on-insulator (SOI) wafers. SOI waveguides are so versatile and the technology built around it is so mature and popular that silicon photonics is almost regarded as synonymous with SOI photonics.

Silicon-on-Insulator Wafers with Buried Cavities [PDF]

Journal of The Electrochemical Society, 2006
Direct bonding and mechanical thinning of pre-etched silicon wafers have been studied for the fabrication of silicon-on-insulator (SOI) wafers with buried cavities. The thin Si diaphragm over the cavity is deflected downward during the grinding and polishing, as the thinning is carried out without supporting the diaphragm.

Biosensors in silicon on insulator

SPIE Proceedings, 2009
We present several nanophotonic biosensors on silicon-on-insulator: ring resonator based devices, slotted ring resonators to increase the interaction between light and the sample, and finally devices based on nanoplasmonic interferometers.

Thickness measurement on insulating silicon oxide layers on silicon structures with dielectric insulation [PDF]

Measurement Techniques, 1983
Interference is among the commonest methods of measuring epitaxial film thicknesses [i, 2]. Spectrophotometers working in the visible and infrared regions are used [3]. The measurements involve determining the positions of the interference maxima in the reflection spectra. The effects of factors that influence the accuracy are closely known [4].
