A significant decrease in resistivity by 55% under blue lighting with ~0.4 J·mm−2 energy density is demonstrated amorphous film of metal-insulator NdNiO3 at room temperature. This large negative photoresistivity contrasts a small positive 8% epitaxial the same illumination conditions. The magnitude rises increasing power or decreasing wavelength light. By combining analysis observed photoresist...

Indium tin oxide thin films with different thicknesses were deposited on polymer substrates, held at room temperature, using electron beam evaporation. The dependence of structural properties, optical properties and room temperature resistivity on the indium tin oxide film thickness was studied. X-ray diffraction illustrates the amorphous structure for all the indium tin oxide prepared films. T...

We report on the amorphous-to-crystalline phase transformation of rubrene thin films. The crystallization of the organic thin films displays disk-like domains whose nucleation and growth follow phase transformation kinetics well-established for inorganic materials under certain time and temperature conditions. We understood that the crystallization of amorphous rubrene thin film shows site-satu...

this study investigated the effect of different concentrations of nanocrystalline cellulose (ncc) on the physical properties of starch-ncc nanocomposites. the nanoparticle distribution in the polymer matrix was investigated using x-ray diffraction. the heat resistance and mechanical properties of the film were measured by differential scanning calorimetry and tensile testing. investigation of n...

Commercial aluminium and stainless steel sheets were used as substrates for thin film silicon solar cell deposition. The influence of elemental contamination and disturbed film growth on solar cell performance and yield were studied. Diffusion during film growth was found to be more pronounced than thermally activated interdiffusion of existing films. Surface irregularities of the substrate are...

The effects of electrical current stressing on the field emission characteristics of hydrogenated amorphous carbon (a-C:H) thin films are reported. In these a-C:H films an initial conditioning treatment of the film is often required before the onset of stable emission and only after several voltage cycles do the values of the threshold field tend to converge. By stressing of the film by applyin...
