The effect of HCl addition on the structural, electrical, and optical properties of p-type silicon films, prepared by hot-wire chemical vapor deposition (HWCVD), was investigated. As the ratio of HCl to SiH4 increased, the amount of amorphous silicon decreased and the crystalline volume fraction...

This article examines the temperature-dependent conduction mechanism in graphene oxide (GO) and thick reduced graphene oxide (rGO) film. The mild oxidation method is used for GO synthesis which is then chemically reduced to obtain rGO and characterized by x-ray diffraction (XRD), scanning...

The structural features and gasification reactivity of chars derived from pyrolysis of a bituminous coal under Ar (Ar char) and CO2 atmosphere (CO2 char) have been investigated, respectively. The pyrolysis was performed in a fixed bed reactor at a final temperature of 700 °C and pressures...

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...

Plasma-enhanced chemical vapor deposition has been used to synthesize diamond-like carbon (DLC) thin films. High purity argon and methane gases were used as precursors for the fabrication of the DLC films. The influence of plasma pretreatment on the growth of the DLC films has been studied by...

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 results of drill stem tests made on the autochthonous Miocene deposits of the Upper Badenian - Lower Sarmatian age in the Carpathian Foredeep were analyzed. Reservoir tests were performed in open and cased holes, where inflows of formation water of varying saturation degree and sometimes...
