TWIN ENGINEERING TO IMPROVE THE SWITCHABILITY AND ROTATABILITY OF POLARIZATIONS AND DOMAINS IN FERROELECTRIC AND PIEZOELECTRIC MATERIALS |
| 摘要 |
A method and device for forming deformation crystal twins in piezoelectric materials that includes deforming and heating the piezoelectric material in an oxidative atmosphere to a predetermined temperature for a predetermined time. The crystalline piezoelectric material is then allowed to cool to room temperature and the deformation is removed. |

1. A method for forming deformation crystal twins in piezoelectric materials, the method comprising:
obtaining crystalline piezoelectric material; deforming the crystalline piezoelectric material using a load; heating the deformed crystalline piezoelectric material in an oxidative atmosphere to a predetermined temperature for a predetermined time to form a plurality of deformation crystal twins in the crystalline piezoelectric material; allowing the crystalline piezoelectric material to cool to room temperature; and removing the load that induces the deformation of the crystalline piezoelectric material. |
