Abstract:
1. A method of stabilizing a frequency or a piezoelectric vibration element, comprising: disposing the piezoelectric vibration element in an atmosphere of a vapor of a ring-shaped dimethylpolysiloxane molecule, the piezoelectric vibration element having a metal layer on a surface of a piezoelectric substrate formed of a thickness shear based piezoelectric material, the metal layer comprising a metal material including a dangling bond, the ring-shaped dimethylpolysiloxane molecule including a nonbonding electron pair; and making the ring-shaped dimethylpolysiloxane molecule subject to chemical absorption with a surface of the metal layer to form a monomolecular layer of the ring-shaped dimethylpolysiloxane molecule, in which the nonbonding electron pair is chemically absorbed to the dangling bond.
