“…All the films exhibit monoclinic structure of VO 2 (PDF No. 43-1051) [23]. For all the films, the (011) peak seems to be of higher intensity than the other peaks, revealing a preferential growth along (011) facet.…”

Preparing the thermal-sensitive thin films with high temperature coefficient of resistance (TCR) and low resistivity by a highly compatible process is favorable for increasing the sensitivity of microbolometers with small pixels. Here, we report an effective and process-compatible approach for preparing V 1-x-y Ti x Ru y O 2 thermal-sensitive thin films with monoclinic structure, high TCR, and low resistivity through a reactive sputtering process followed by annealing in oxygen atmosphere at 400°C. X-ray photoelectron spectroscopy demonstrates that Ti 4+ and Ru 4+ ions are combined into VO 2. X-ray diffraction, Raman spectroscopy, and transmission electron microscopy reveal that V 1-x-y Ti x Ru y O 2 thin films have a monoclinic lattice structure as undoped VO 2. But V 1-x-y Ti x Ru y O 2 thin films exhibit no-SMT feature from room temperature (RT) to 106°C due to the pinning effect of high-concentration Ti in monoclinic lattice. Moreover, RT resistivity of the V 0.8163 Ti 0.165 Ru 0.0187 O 2 thin film is only one-eighth of undoped VO 2 thin film, and its TCR is as high as 3.47%/°C.

The modified CeO2 was prepared by a chemical surface modification method. The action of CeO2 powders in EPDM composites contain 10 phr modified clay was studied. The effects of content and surface modification of CeO2 powders on the properties of the EPDM composites containing 10 phr modified clay rubber was discussed. The results showed that the mechanical, volume resistivity and thermal properties of EPDM rubber filled with the modified CeO2 increased by loading of modified CeO2. And the tensile strength of EPDM composites containing modified CeO2 is higher than that with the unmodified CeO2. The surface of modified CeO2 powders had a hydrophobic organized layer which could increase interface cohesion with the rubber and dispersity in rubber resulting in exerting reinforcement effect. The effect of coagent on the physical and thermal properties of EPDM rubber composites was studied. The results showed that the physical and thermal properties of EPDM rubber composites increased with the addition of the coagent due to the increase of the crosslinking density. J. VINYL ADDIT.

“…Enormous efforts have been made to shift the phase transition temperature to the proximity of room temperature. Elemental doping has been employed as an effective technique to modify the phase transition temperature of VO 2 thin films [12][13][14][15][16][17][18][19].…”

The phase transition temperature of vanadium dioxide (VO 2) thin films shifts to the vicinity of room temperature by reducing the dimensions from microscale to nanoscale without the use of any dopant. This quantum size effect elucidated by studying the structural, optical and electrical properties of nanothin and microthin films of VO 2 across their semiconductor-metal phase transitions has been demonstrated in this reported work. The films fabricated on glass substrates via the inorganic sol-gel route were characterised by Rutherford backscattering spectrometry (RBS), X-ray diffractometery, scanning electron microscopy, ultraviolet-visible spectroscopy and the four-probe method. The RBS results estimate a layer thickness of 15 and 291 nm for nanothin and microthin films, respectively. The films were polycrystalline in their nature of [011] orientation with regular and irregular crystallites of a cuboidal surface morphology. Estimation of crystallite size revealed that nanothin films attain poor crystallinity as compared with microthin films. The blue shift was observed in nanothin films from microthin films as maximum absorption occurred at wavelengths of 360 and 443 nm, respectively. Optical bandgaps of 2.3 and 1.87 eV were found for nanothin and microthin films, respectively. Depletion in metal-to-semiconductor and semiconductor-tometal transition temperatures were experienced from higher temperature regimes of 341 and 335 K for microthin films to lower temperature regimes of 319 and 305 K for nanothin films, respectively.
