Photoelectrochemical investigation on spray depositedn-CdIn2S4 thin films

Characterization of Spray Pyrolysed CuInS2 Thin Films

An indigenously developed chemical spray pyrolysis system was used to deposit polycrystalline CuInS2 thin films. It was found that smaller spray rate results in films with better crystallinity and lower resistivity. Increase in surface roughness of the films was observed for higher spray rates. Variations in film stoichiometry with composition of spray solution were analyzed along with its opto...

Photoelectrochemical Performance Observed in Mn-Doped BiFeO3 Heterostructured Thin Films

Pure BiFeO₃ and heterostructured BiFeO₃/BiFe0.95Mn0.05O₃ (5% Mn-doped BiFeO₃) thin films have been prepared by a chemical deposition method. The band structures and photosensitive properties of these films have been investigated elaborately. Pure BiFeO₃ films showed stable and strong response to photo illumination (open circuit potential kept -0.18 V, short circuit photocurrent density was -0.0...

Laboratory Investigation of Support Mechanism for Thin Spray-on Liners

ABSTRACT: Rock support is the basis of any underground mine and many open cut operations. Ground support methods have evolved over the years with the current trend to use bolts, mesh and shotcrete. Thin spray-on liners may be the next step replacing mesh and shotcrete, however being a relatively new product is not well understood and no standard testing procedures exist to determine the strengt...

Structural, optical and photoelectrochemical characterizations of monoclinic Ta3N5 thin films.

Monoclinic Ta3N5 thin films were synthesized by thermal nitridation of amorphous Ta2O5 films directly sputtered by radio frequency magnetron sputtering. The samples were studied by high resolution transmission electron microscopy, X-ray photoelectron spectroscopy, UV-Vis-NIR spectrophotometry, rietveld refinements, spectroscopic ellipsometry and electrochemical techniques. The surface compositi...
