Using Nd:YAG pulsed laser deposition, the modulation of the residual stress in thin films of ZnO and their effect on the electrical properties was studied. The variations of residual stress were correlated with the number of oxygen atoms grabbed in t

The glancing angle Deposition (GLAD) technique was used to grow cadmium sulfide (CdS) thin films on glass and indium tin oxide (ITO) coated glass substrates from a sublimate vapor effusion source. The samples were prepared under different incident de

ZnO thin films were deposited on ITO/glass substrates by pulsed laser deposition (PLD) using two different kinds of targets. One of the targets was made of pure ZnO powder and the other one consisted of a mixture of ZnO powder with cyanoacrylate glue

We report an alternative method to evaluate transparent conductor oxides (TCO) from their photonic flux density (PFD(hυ)) to be used in solar cells. From the transmittance spectrum (T(hυ)) in the visible region, we calculate the PFD(hυ) and the so

The main motivation of this work is to deposit two different metals (gold and silver) on titanium oxide nanoparticles surface in a one-step simple and fast physical process by applying a nitrogen plasma as the main source of nitrogen atoms to obtain

We study the thermal diffusion through a fluid made of diamond microparticles immersed in a ferrofluid. A thermal conductivity enhancement is observed when a magnetic field is applied to the fluid; this phenomenon is due to a better heat propagation

Magneto-optic phenomena in ferrofluids have been shown to be related to the formation of chain structures, due to the arrangement of the ferromagnetic particles, induced by an applied magnetic field. In this work, the effects on transmission of polar

In this work, the development of a new crystallization technique is reported, using nitrogen plasma (AC) to obtain nanostructured anatase and rutile from amorphous titanium oxide (TiO2). This methodology increases throughput and minimizes thermal eff
