A dual-core photonic crystal fiber (DC-PCF) sensor based on fiber Mach-Zehnder interferometer is proposed and demonstrated for stress sensing with a sensitivity of 1.4 pm/μe and hydraulic pressure… (More)
Utilizing the balance of capillary forces and adhesion, a liquid material, e.g. photo resist, can be applied to the surface of a face down mounted substrate. STEAG HamaTech's Advanced single… (More)
Abstract The near-infrared emission from Er and Si codoped ZnO film, synthesized by cosputtering from separated Er, Si, and ZnO targets, has been investigated. By building the multilayer film… (More)
A new method, metal vapour vacuum arc ion source implantation, has been developed to synthesize Er-doped Si-rich SiOx thin films under relatively low implanted ion energies and very high doses. An Er… (More)
Abstract SiO2 thin films containing nanocrystalline Si (nc-Si) and Er ions have been fabricated by using a metal vapor vacuum arc (MEVVA) ion source. Photoluminescence (PL) properties of the films… (More)
Abstract Strong ultra-violet and visible frequency up-conversion fluorescence spectroscopy in neodymium-ion implantation single crystalline silicon at the excitation wavelengths of 625, 650, 675 and… (More)
Graphene nanomaterials exhibit excellent optical properties when interacting with electromagnetical fields, which plays an important role in a wide range of applications such as optical communicati...
Dual implantation of erbium and silicon into thermally grown SiO2 film on Si was performed using a metal vapour vacuum arc ion source; this was followed by rapid thermal annealing at 500–1100°C for… (More)
Good dispersibility and proper structural strength are both critical to the use of nanomaterials as lubricant additives to improve antiwear and friction-reducing ability. Herein we report the… (More)
