Title: Polarity inspecting method
Inventor: FUJII SHINZO
IPC: G01N25/00
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To inspect the direction of polarization of a surface to be measured through simple operations without through any troublesome process by changing the magnitude of spontaneous polarization by changing the temperature of a ferroelectric single crystal and detecting the polarity of the charges on the surface of the crystal. SOLUTION: The charges 3 on the surface of a dielectric single crystal 1 (for example, BaTiO3 ) are neutralized by causing spontaneous polarization 2 at a room temperature T (K) by jetting air upon the surface of the crystal 1. Immediately after the crystal is heated to a temperature T+ΔT from the neutralized state, the surface charges 3 become negative on the top side, because negative charges increase, and become positive on the bottom side, because positive charges increase. The polarity of the crystal 1 is inspected by detecting the then polarity of the charges 3 existing on the surface of the crystal 1 with an electrostatic tester.  Since the polarity of the surface charges 3 is detected at each point by scanning the surface of the crystal 1 with the electrostatic tester in such a way, whether or not the polarity of spontaneous polarization 2 on the surface of the crystal 1 is the same can be inspected easily.
