Investigation of local structure effect and X-ray absorption characteristics (EXAFS) of Fe (Ti) K-edge on photocatalyst properties of SrTi(1−x)FexO(3−δ)
In this study, the STFx photocatalyst powder was synthesized with a high temperature solid state reaction. The microstructures and surface of samples were characterized by X-ray diffraction (XRD), scanning electron microscopy ...
Positive bias-induced Vth instability in graphene field effect transistors
In this letter, we report positive bias-induced Vth instability in single and multilayer graphene field effect transistors (GFETs) with back-gate SiO2 dielectric. The ΔVth of GFETs increases as stressing time and voltage ...
Electrochromic cell with UV-curable electrolyte polymer for cohesion and strength
Electrically colourable (“electrochromic”) windows, hitherto confined to small areas, have recently been much expanded in area in new aircraft windows. Reviews indicate that to extend such high-tech applications to more ...
Radially graded index whispering gallery mode resonator for penetration enhancement
This paper theoretically analyzes a hollow cylindrical whispering gallery mode resonator with radially inhomogeneous cladding. We propose an index profile of n(r) = b/r to enhance field penetration towards the resonator ...
