| Abstract(in English) | Piezoelectricity was produced in super-lattice silica films with tetravalent metal dopants by poling. Tetravalent-metal-doped SiOa (M^<4+>:SiO_2) films were prepared on Si substrates by RF magnetron sputtering. We used germanium, titanium, and tin as doping materials. The piezoelectricity of the films was compared with the piezoelectricity of quartz. Piezoelectricity of the same order of magnitude as that in quartz was observed in the M^<4+>:SiO_2 films. However, less than a week later, the piezoelectricity disappeared almost completely in all the samples. We developed a pinning technique based on the structure of a Ge:SiO_2 - Ti:SiO_2 - Sn:SiO_2 -super-lattice. This super-lattice structure was very effective in preventing the piezoelectricity from disappearing. Furthermore, broad band visible light emission was observed in the proposed super-lattice film. |
