Abstract

<p>Compact devices for high electric field generator using a different aspect ratio of pyroelectric LiTaO3 single crystal and a Peltier device were assembled. Measurement of X-ray emitted upon the thermal changing was carried out to evaluate the induced electric field onto surface of the z-plane of LiTaO3. The formed electric field per length of the z-axis for thin-type (10 × 10 × 2 mm) was twice larger than that of pillar-type (3 × 3 × 10 mm). The attachment of Pt foil onto the surface of z-plane little affected on X-ray emission behavior. The flange-type generator with thin-type LiTaO3 single crystal was also assembled to construct a reactor for chemical reactions with induced high electric field of a pyroelectric crystal. The outgassing behavior from a reaction vessel was examined.</p>
