Wide-range (0.33%–100%) 3C–SiC resistive hydrogen gas sensor development
TL;DR: In this article, NiCr planar ohmic contacts were deposited on both a 4μm 3C-SiC epitaxial film grown on n-type Si(001) and directly on Si to form the resistive sensor structures.

TL;DR: In this article, an addition to the present model found in many Spice type environments, Jiles-Atherton, is the subject of this work, which adds such a dependence on temperature first followed by frequency.
Hydrogen Gas Sensors using 3C-SiC/Si Epitaxial Layers
TL;DR: A hydrogen gas sensor consisting of planar electrical NiCr contacts formed on the surface of a 3C-SiC epitaxial layer grown on Si(001) has been fabricated and tested.

Spin-On Doping of Porous SiC with Er
TL;DR: In this paper, a spin-on doping technique was applied for Er incorporation into porous SiC and a distinct Er PL peak close to 1.53 μm appeared after the formation of an Er containing spinon diffusion source followed by a drive-in thermal annealing step at 1100C.
