  • Compaction of lead zirconate titanate sol-gel coatings. 
    Khan, Mikael A.; Kurchania, Rajnish; Corkovic, Silvana; Zhang, Qi; Milne, Steven J. (Elsevier Science B.V., Amsterdam., 2006-06-01)
    A novel method for the densification of sol-gel films is presented. After elimination of organic decomposition products by heat-treatment at 350 °C and 450 °C, the films are isopressed prior to crystallisation at 550 ...

  • Development of residual stress in sol-gel derived Pb(Zr,Ti)O3 films: An experimental study 
    Corkovic, Silvana; Zhang, Qi (American Institute of Physics, 2008-04-30)
    Residual stresses develop in the sol-gel-derived ferroelectric thin films during the transformation of the metalorganic gel to the metal oxide upon thermal treatment and due to the thermal and elastic mismatch between the ...
  • Enhanced pyroelectric coefficient of antiferroelectric-ferroelectric bilayer thin films 
    Corkovic, Silvana; Zhang, Qi (American Institute of Physics, 2009-12-31)
    In this study, the pyroelectric coefficient and the figure of merit (FOM) of the ferroelectric PbZr0.3Ti0.7O3 (PZT 30/70) thin films were found to be greatly enhanced by introducing a thin antiferroelectric PbZr0.95Ti0.05O3 ...
  • Piezoelectric thick films for microelectromechanical systems application 
    Corkovic, Silvana (Cranfield University, 2007-03)
    This thesis concerns the processing and characterization of thick PZT sol-gel films for potential applications in MEMS devices. The deposition method was spin-coating. The aim was to reduce the number of coatings in the ...
