Ce1-xFexO2 (x=0, 0.01, 0.03 and 0.0 5) thin films were grown by pulsed laser deposition technique on Si and LaAlO3 (LAO) substrates. These films were deposited in vacuum and 200 mTorr oxygen partial pressure for both the substrates. These films were characterized by x-ray diffraction XRD and Raman spectroscopy measurements. XRD results reveal that these films are single phase. Raman results show F2g mode at ~466 cm-1 and defect peak at 489 cm-1 for film that deposited on LAO substrates, full width at half maximum (FWHM) is increasing with Fe doping for films deposited on both the substrates.

AbstractRecent advances in doping and substitutional alloying of bulk skutterudite phases based on the CoAs3 structure have yielded compositions with high thermoelectric figures-of-merit (“ZT”). It is postulated that further enhancements in ZT may be attained in artificially-structured skutterudites by engineering the microstructure to enhance carrier mobility while suppressing the phonon component of the thermal conductivity. This work describes the growth of single-phase skutterudite thin films (CoSb3 and IrSb3) by pulsed laser deposition. A substrate temperature of 250°C has been found to be optimal for the deposition of the skutterudites from stoichiometric targets. Above this temperature, the film is depleted of antimony due to its high vapor pressure. However, when films are grown from antimony-rich targets, the substrate temperature can be increased to at least 350°C without losing the skutterudite phase. Films from both target types were characterized with X-ray diffraction and Rutherford-Back-Scattering (RBS) to reveal structure and stoichiometry. Some preliminary electrical measurements will also be shown.

Diamond thin films were grown on diamond (100) substrates in oxygen atmospheres by pulsed laser deposition (PLD) using an ArF excimer laser. The suitable oxygen atmosphere of 5 × 10-2 Torr can etch the sp2 bonding fractions preferentially. At substrate temperatures between 550°C and 650°C, single-phase diamond films consisting of diamond crystal with diameters of 1 - 5 μm could be grown. The results demonstrated that the diamond thin films can be grown homoepitaxially using PLD by controlling the deposition parameters, such as the oxygen pressure and the substrate temperature.

Cu2ZnSnS4 (CZTS) is a complex quaternary material, and obtaining a single-phase CZTS with no secondary phases is known to be challenging and dependent on the production technique. This work involves the synthesis and characterization of CZTS absorber layers for solar cells. Thin films were deposited on Si and glass substrates by a combined magnetron sputtering (MS) and pulsed laser deposition (PLD) hybrid system, followed by annealing without and with sulfur powder at 500 °C under argon (Ar) flow. Three different Cu2S, SnS2, and ZnS targets were used each time, employing a different target for PLD and the two others for MS. The effect of the different target arrangements and the role of annealing and/or sulfurization treatment were investigated. The characterization of the absorber films was performed by grazing incidence X-ray diffraction (GIXRD), X-ray reflectometry (XRR), Raman spectroscopy, scanning electron microscopy, and regular transmission spectroscopy. The film with ZnS deposited by PLD and SnS2 and Cu2S by MS was found to be the best for obtaining a single CZTS phase, with uniform surface morphology, a nearly stoichiometric composition, and an optimal band gap of 1.40 eV. These results show that a new method that combines the advantages of both MS and PLD techniques was successfully used to obtain single-phase Cu2ZnSnS4 films for solar cell applications.

AbstractThe ferroelectric (Pb, La) (Zr,Ti)03 (PLZT(9.4/65/35)) optical waveguiding thin films have been prepared on SiO2 coated Si and on silica glass substrates by pulsed laser deposition. X-ray θ–2θ scans revealed that the films are single-phase pseudo-cubic perovskite. The surface chemical composition of the as grown films were determined by XPS. The ferroelectric properties of the films as grown on Pt/Ti coated silicon were demonstrated by using a modified Sawyer-Tower circuit, and the optical waveguiding properties of the films were characterized by using a rutile prism coupling method. The as grown films have an average transmittance of 80% in the wavelength range of 400˜2000nm and a refractive index of 2.2 at 632.8mn close to the bulk PLZT. The distinct m-lines of the guided TM and TE modes of the films as grown on SiO2 coated Si substrates have been observed.
