Influence of post-deposition thermal annealing on the properties of pulsed laser deposited tungsten layers K J Lethy, R Vinod Kumar, S Potdar et al.In this investigation, silver (Ag) films of varying thickness (25-100 nm) were grown on cupric oxide (CuO) on silicon and quartz. The CuO preparation was carried out by the thermal oxidation annealing of copper (Cu) thin films deposited by DC magnetron sputtering. The physical properties of the prepared films were studied by different techniques. Rutherford backscattering spectroscopy (RBS) analysis indicated that the Ag film thickness was about 25-100 nm. X-ray diffraction (XRD) results showed that by increasing Ag thickness, the film crystallinity was improved. Also, atomic force microscopy (AFM) and scanning electron microscopy (SEM) results demonstrated that the surface morphology and the grain size were affected by the Ag film thickness. Furthermore, the electrical resistivity of films determined by four-point probe measurements versus the Ag film thickness was discussed. A reduction in the optical band gap energy of CuO is observed from 1.51 to 1.42 eV with an increase in Ag film thickness to 40 nm in Ag/CuO films.

“…As an important p-type semiconductor metal oxide with a narrow band gap (1.2-1.5 eV), copper oxide (CuO) has drawn increasing research attention due to its attractive properties like nontoxicity, excellent reactivity, chemical stability, electrochemical activity, low production cost and abundant availability, and has been widely used in diverse applications like gas sensors, solar cells, field emissions, Li-batteries, supercapacitors, and catalysis [4][5][6][7][8][9]. Unfortunately, the reports on the photodegradation of organic dyes using CuO as photocatalyst is limited as the activity of pure CuO is not high enough due to the fast recombination of photogenerated electron-hole pairs [10][11][12][13][14][15][16]. An effective approach to overcome this barrier is to couple CuO with another semiconductor material since coupling two semiconductors with different energy levels results in mutual transfer of photogenerated electrons and holes from one semiconductor to the other, resulting in an efficient charge separation, an increased lifetime Page 6 of 30 A c c e p t e d M a n u s c r i p t 5 of the charge carriers, and an enhanced interfacial charge transfer to adsorbed substrates.…”
