| titleOfInvention | Method of reversing polarization of ferroelectric crystal and fabrication method of polarization reversal lattice |
| abstract | PROBLEM TO BE SOLVED: To provide a polarization reversal method of a ferroelectric crystal and a method for producing a polarization reversal lattice capable of causing polarization reversal from the front surface to the back surface of the ferroelectric crystal in a very simple and low cost and stably. provide. A photoconductive film 20 is formed on the upper surface of a ferroelectric crystal plate 10. Then, the ultraviolet light 70 whose intensity distribution in the photoconductive film 20 has a periodic pattern is irradiated to the ferroelectric crystal plate 10 through the photoconductive film 20 and at the same time, the ferroelectric material through the photoconductive film 20. An electric field is applied to the crystal plate 10. Since the region 20 a irradiated with the ultraviolet light 70 exhibits conductivity, the photoconductive film 20 functions as an electrode corresponding to the periodic pattern of the ultraviolet light 70. Therefore, a polarization structure is generated inside the ferroelectric crystal plate 10 corresponding to the periodic pattern similar to the electrode, that is, the periodic pattern of the ultraviolet light 70, and as a result, the uniformity is excellent from the front surface to the back surface of the ferroelectric crystal 10. A domain-inverted lattice can be produced. [Selection] Figure 2 |
