Abstract:
AbstractPolarization measurement has been widely used in material characterization, medical diagnosis and remote sensing. However, existing commercial polarization analyzers are either bulky schemes or operate in non-real time. Recently, various polarization analyzers have been reported using metal metasurface structures, which require elaborate fabrication and additional detection devices. In this paper, a compact and fully integrated silicon polarization analyzer with a photonic crystal-like metastructure for polarization manipulation and four subsequent on-chip photodetectors for light-curr

Experiments were carried out on a 6-ton P91 steel ingot in which severe hot tearing was detected in the upper centerline. Another ingot, with a better heat preservation riser, and without hot tearing, was used for comparison. Samples were obtained from the area of the ingot body with hot tearing, and their morphologies were

The study was designed to understand the influence of different atmospheres of plasma gas on hydroxyapatite-coated commercially pure Titanium (Ti) and titanium alloy (Ti-6Al-4V). Ti and Ti-6Al-4V were plasma spray-coated with hydroxyapatite in argon, nitrogen, argon/hydrogen, and nitrogen/hydrogen atmospheres. The microstructure, porosity, calcium to phosphate (Ca-P) ratio, surface roughness, and hardness of the coat were characterized using a scanning electron microscope, energy dispersive spectroscopy, image analyzer, profilometer, and Vickers hardness tester. The analyses of the coatings ob

To investigate the mass composition of the ion beam obtained through field ion emission, a mass analyzer designed analogous to the Wien velocity filter was utilized. This Wien filter analyzer operates based on the principle of intersecting mutually perpendicular electric and magnetic fields (E×B) to classify charged particles according to their mass and charge. The ion beam was obtained using mInSb and InSb0.98Bi0.02 as the working The mass composition of the ion group was analyzed using this method.

Abstract:
In this paper, failure analysis was conducted to investigate the root cause of Ti/Ni/Ag film peeling from silicon wafer surface. SEM and Edax analysis revealed that peeling was found at Ti/Si interface, and no contamination elements, such as C, H, O, were existed. VK Analyzer was used to measure the surface roughness, and the results revealed that the peeling failure was due to the low surface roughness resulted from excessive polishing after wafer back grinding process. Experiments for changing rabbling polishing method for bubbling polishing one were done expecting to realize high uniformity

The mixed metal oxides Bi2MoO6 and La-doped Bi2MoO6 were prepared by the sol–gel method. Then, varying quantities of the as-prepared mixed metal oxides were blended with graphene oxide (GO), employing sonication, to obtain Bi2MoO6/GO (BM/GO) and La-Bi2MoO6/GO (LBM/GO) nanocomposites. These prepared materials were characterized by different techniques such as thermal gravimetric analysis (TGA), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), and transmission electron microscopy (TEM).

In this paper, Cu/SiO2composites with different metal contents were successfully prepared by a selective reduction process. The phase composition and microstructure of composites were analyzed by XRD and SEM, respectively. The results show that spherical copper particles are uniformly distributed in silica matrix. The impedance and permittivity of composites were tested with RF impedance analyzer (0.1~1 GHz). It is indicated Cu/SiO2composites exhibit capacitive character. In addition, the dielectric constants get enlarged due to the enhancement of interface polarization.
