The vanadium pentoxide (V2O5) films were obtained by using sol–gel procedure and then were annealed at different temperature in air. The effect of different annealing temperatures on the composition, the microstructure, the surface morphology and the optical properties of the films were...

A series of Zn1-xMgxO (x = 0 ~ 0.16) films have been prepared on glass substrates by RF magnetron sputtering. The structure, surface morphology, composition, optical and electrical properties of the films were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), energy...

Thin silicon films were deposited by the plasma-enhanced chemical vapour deposition method using microwave (MW) and standard radio frequency (RF) gas discharge in silane gas diluted by hydrogen in the range that produces a mixture of amorphous and crystalline phases. The samples were analysed by...

The nonresonant Raman spectra of infinite peapod were calculated in the framework of bond-polarization theory by using either direct diagonalisation of dynamical matrix or the spectral moments method. The effect of C60-tube interaction on the mode frequencies both of the peas and the pod has...

Boron-doped hydrogenated amorphous carbon (a-C:B:H) thin films have been deposited by radio frequency plasma-enhanced chemical vapor deposition (r.f. PECVD) with a frequency of 13.56 MHz at room temperature using pure methane as a precursor of carbon source mixed with hydrogen (H2) as a carrier...

Diamond-like carbon nanostructures were prepared using Plasma enhanced chemical vapor deposition (PECVD). Temperature dependence of self-assembly of carbon nanostructures is noted. Carbon and silicon exhibit significant lattice mismatch and during the self-assembly, stacking of carbon atoms...

An infrared CO2 laser was used for regional heating to study the heating effect on hot filament chemical vapor deposition of diamond-like carbon formation on Si(100) face substrates. The substrate surface temperature was about 450–500°C. The power of the laser called low, medium, and high...

The photoabsorption edge shifting from UV to visible region accompanied with increased intensity and Raman features change was observed for N+ implanted TiO2. Raman spectra prove the formation of TiNx and oxygen vacancies in the implanted TiO2, which is considered as the origin of absorption...
