  • Abstract
    The dielectrostriction effect of thermal SiO2 was experimentally studied in this paper. A beam bending method was used to apply mechanical stresses on the dielectric and the dielectric constant was characterized by the capacitance of a sandwich structure. A model for extracting the dielectrostriction coefficient, M12, was developed and special samples for the measurements were fabricated. According to the measurements the dielectrostriction coefficient, M12, of thermal SiO2 is -0.19 ± 0.01 × 10-21m2/V2.
