Among various fabrication techniques of thin film, the sol - gel process has gained much interest for the preparation of pzt thin film, due to ihe advantages of good homogeneity, easy control of composition, low in - ill i reaving temperature, easy formation of large area thin films pb ( zrxti : - k ) 0 :, ( pzt ) films were prepared on the ito coated glass plates and low resistor silicon wafer in sol - gel dip - coating process associated wi di heat treatment : at different temperatures and characterized by x - ray diffraction ( xrd ) and transmission electron microscopy ( tem ). lt is shown that the pzt ferroelectric thin films with ( 110 ) preferred orientation and well - crystallized perovskite structure can be obtained after annealing at 680 ? for 30 minutes on ito substrate and at 800 " c for lornin on silicon substrate
