Pulsed laser deposition method was employed to grow MgO thin films with preferred orientation on bare Si(100) and SiO2/Si(100) substrates. The orientation of MgO thin films was systematically investigated by varying deposition parameters. XRD analysis showed that the preferred orientation of MgO thin films would change from (111) to (100) when laser fluence decreased and oxygen pressure increas...

An apparent kinetic model is developed for a novel chemical vapor deposition (CVD) process of silicon oxynitride (SiOxNy) films from tris(dimethylsilyl)amine (TDMSA) and O2, operating at moderate temperature (600–650 °C) atmospheric pressure. The definition reaction pathways the extraction information based on recently reported results gas phase composition, complemented by solid characteristic...

Cu(In,Ga)Se2 thin films (CIGS) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of Co-evaporated metallic precursors in Se-containing environment under N2 gas flow. Structural properties of prepared thin film were studied. To characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

Owing amongst other to its high electron mobility, fullerene C70, has been widely used as an electron transporting layer in organic solar cells. In this research, we report the use of C70 thin films as electron transport layers of planar perovskite solar cells (PSCs) using a conventional device structure. The thickness of the C70 layer has been optimized to achieve the best efficiency of 12%. I...

Composite thin films based on carbon nanotubes have received immense attention which is attributed to their distinct mechanical, thermal, optical and structure properties. Depending on the film compositions and preparation methods, carbon nanotube based thin films can be tuned for various applications in many fields. In this comprehensive review paper, we overview the recent methods for the fab...

the ac electrical behaviour of nano porous silicon (psi) with tio2 thin films was examined over the range of frequency 102 to 105 hz. porous silicon (psi) layers were obtained by electrochemical etching in hf solution and tio2 thin films were deposited on psi substrates by using electron beam evaporation technique at room temperature. the porosity of psi layer was found by using the gravimetric...

Highly c-axis oriented apatite-type lanthanum silicate (LSO) thin films were fabricated by a simple solution coating method. In the solution coating method, LSO thin films are obtained by crystallization of initially deposited amorphous LSO precursor thin films. The degree of orientation was influenced by the precursor morphologies and a dense LSO precursor led to a high c-axis orientation perp...
