Excimer laser deposition of c-axis oriented Pb(Zr, Ti)O_3 thin films on silicon substrates with direct-current glow discharge

Ferroelectric thin films of Pb(Zr, Ti)O_3 (PZT) were fabricated on platinum-coated silicon using the process of direct-current glow discharge assisted laser deposition, where the substrate was electrically grounded. The films deposited at 730 °C with + 800 V discharge voltage are oriented mostly with the c -axis perpendicular to the substrate surface, and exhibit good ferroelectric hysteresis loops. A possible mechanism for the improvement of the deposition process has been proposed.
