Comparative studies of relaxor-ferroelectric Pb0.92La0.08(Zr0.52Ti0.48)O3 thin films deposited by pulsed laser deposition and sol-gel spin coating

Effects of Cobalt Doping on Optical Properties of ZnO Thin Films Deposited by Sol–Gel Spin Coating Technique

Cobalt (Co) doped Zinc Oxide (ZnO) thin films, containing different amountof Cobalt nanoparticles as the Co doping source, deposited by the sol–gel spin coatingmethod onto glass via annealing temperature at 400˚C, have been investigated by opticalcharacterization method. The effect of Co incorporation on the surface morphology wasclearly observed from scanning electron microscopy (SEM) images. ...

Tin-doped indium oxide thin films deposited by sol–gel dip-coating technique

Indium tin oxide (ITO) thin films were prepared by the sol–gel dip-coating (SGDC) technique. The microstructure and electrical properties of ITO thin films crystallized using rapid thermal annealing (RTA) were compared with those of films prepared by classic thermal annealing (CTA). ITO thin films were successfully prepared by CTA at 500 jC for 30–60 min. At the same temperature of 500 jC and w...

Stress effects in sol-gel derived ferroelectric thin films

Residual stress development during processing of sol-gel derived ferroelectric thin films influences electromechanical properties and performance. The present work investigates the effects of stress on field-induced polarization switching in ferroelectric Pb~Zr0.52Ti0.48)O3 ~PZT! ~52/48! thin films. Film response is measured as a function of externally applied mechanical stress using a double-b...

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...
