Effect of Pt bottom electrode texture selection on the tetragonality and physical properties of Ba0.8Sr0.2TiO3 thin films produced by pulsed laser deposition J. Appl. Phys. 112, 044105 (2012); 10.1063/1.4748288 Structural, electrical, and magnetic properties of Mo 1 − x Fe x O 2 ( x = 0 -0.05 ) thin films grown by pulsed laser ablationHighly crystalline thin films of MoS 2 were prepared over large area by pulsed laser deposition down to a single monolayer on Al 2 O 3 (0001), GaN (0001), and SiC-6H (0001) substrates. X-ray diffraction and selected area electron diffraction studies show that the films are quasi-epitaxial with good out-of-plane texture. In addition, the thin films were observed to be highly crystalline with rocking curve full width half maxima of 0.01 , smooth with a RMS roughness of 0.27 nm, and uniform in thickness based on Raman spectroscopy. From transport measurements, the as-grown films were found to be p-type. V C 2015 AIP Publishing LLC. [http://dx.

The present study deals with the optical properties of copper sulphide films obtained by the spray pyrolysis technique. Films deposited at 250 "C substrate temperature have Cu2S chalcocite as the dominant phase. The films are stable and have good adhesive properties. Optical constants of the films are calculated from the measured reflectance, transmittance and thickness data using the iteration method. The films have an indirect band gap of 1 .O and a direct band gap of 1.9 eV. Films deposited on aluminium substrates work as solar selective absorbers of the semiconductorimetal tandem type with maximum solar absorption (as) of 0.89 and minimum thermal emittance ( E ~) of 0.25.

High absorptance and low thermal emittance selective surfaces have been formed by evaporating lead sulphide onto Al evaporated Al substrates. The dependence of selectivity, α/ϵ, on thickness has been studied. The maximum selectivity was obtained for PbS thickness of 400 Å. The emissivity is found to increase with temperature. The coatings are stable up to a temperature of 240°C in air. Long term ultraviolet irradiation causes the photo‐oxidation of PbS to PbSO4 which results in the increase of emittance and a decrease in absorptance. When cycled between 0°C and 200°C, the coatings do not show any signs of degradation.
