IPC: G01Q60/24
Filed: 2008-06-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a physical-property measuring method for easily measuring an accurate value of a transverse piezoelectric constant d31 in a piezoelectric thin-film, and a device for measuring a physical property in a piezoelectric thin-film.  <P>SOLUTION: A lower electrode and a piezoelectric thin-film, being a piezoelectric material with a thickness t, overlie a substrate in this order to keep a rectangular or square upper electrode having at least a pair of mutually opposing sides each having a thickness t deposited on the piezoelectric thin-film, thereby forming a specimen. The specimen is placed on a specimen support such that the sides, each having a thickness t, of the upper electrode are aligned with a first direction. A probe is located at the endmost part in a first direction. A prescribed voltage V is applied across the lower electrode and the upper electrode so as to displace the piezoelectric thin-film. The specimen support is driven in a first direction by making it follow the displacement of the probe so as to cancel a change in the positional relationship between the probe and the upper electrode caused by the displacement. A displacement ΔS in a first direction of the piezoelectric thin-film is calculated on the basis of the drive amount so as to calculate a transverse piezoelectric constant d31 of the piezoelectric thin-film.  <P>COPYRIGHT: (C)2010,JPO&INPIT
