“…It is also confirmed from these images that the uniformity of films improves with increase in thickness. The change in morphology with thickness is also observed in Cu x S y O z thin film [32].…”

Molybdenum oxide ( MoO 3 ) is a chromogenic and a wide band gap n-type semiconductor. Thickness of thin films is usually observed to have significant influence on various properties of chromogenic materials. MoO 3 thin films of different thicknesses (100 nm, 200 nm and 400 nm) were deposited on glass substrates by thermal evaporation technique. The effect of thickness of deposited thin films on the structural, morphological and optical properties was investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM) and UV-visible spectroscopy. XRD analysis revealed the amorphous nature of deposited thin films of different thicknesses. FTIR spectrum showed the characteristic vibrations of intermolecular bonds in molybdenum oxide. The surface morphology of MoO 3 films showed nanoflakes like structures which became densely stacked with increase in film thickness and transformed to large grains with uniform coverage of the substrate surface with randomly oriented morphology. The transmission spectra revealed the slight increase in average transmittance in the visible-NIR region with increase in thickness of thin films. The optical band gap of the deposited thin films of different thicknesses was found to be increasing with increase in thickness of the films which may be attributed to decreased defect centres. The decrease in the values of Urbach energy with increase in thickness may be due to the increased homogeneity and decrease in scattering centres.

“…It suggests that at least for Cu, films deposited from NWs have higher thermal stability than magnetron-deposited films. Note that the film stability depends not only on the annealing temperature, but also on the film thickness: compared magnetron deposited Cu film was 112 nm thick, and Cu NWs film has apparent thickness 110 nm; for films of different thickness stability results can differ [26].…”

“…A possible scheme for the growth mechanism of CuS/TeO 2 NWs is shown in figures 5(a)-(c). During the first heating steps some parts of CuS layer surface may form islands (irregular droplets) and may be subject of oxidation and sulfur removal [24,33,34]. The droplets are able to capture the Te and O volatiles transported by the Ar flux, forming an eutectic alloy.…”

The current work concerns with the effects of cupper sulfide (CuS) buffer layer on morphological, structural and optical properties of tellurium dioxide (TeO2) nanostructured thin films synthesized by vapor transport method. Single crystalline tetragonal TeO2 crystallographic phase with enhanced peak intensity and crystallinity for CuS/TeO2 film are observed by X-ray diffraction analysis. Scanning electron microscopy examinations revealed small rod-like morphology for TeO2 and randomly oriented nanowires morphology for CuS/TeO2 samples. The estimated optical band gap energies were 3.78 and 3.63 eV for TeO2 and CuS/TeO2 nanostructured films, respectively. The photoluminescence of CuS/TeO2 film was enhanced and red-shifted from 450 to 455 nm by the presence of CuS layer. The effective charge carrier life times were 0.14 ns and 1.92 ns for TeO2 and CuS/TeO2 films, respectively. These results could be beneficial for optoelectronic devices such as light emitting devices.
