METHOD OF MODIFYING THE TEMPERATURE DRIFT OF THE PROPAGATION TIME OF SURFACE ELASTIC WAVES AND A DEVICE OBTAINED BY SAID METHOD |
| 摘要 |
<p>The present invention relates to the modification of the temperature-induced drift in propagation time of surface elastic waves. The invention proposes to achieve this modification by selecting a suitable crystal cut of the crystalline substrate, and carrying out a localised ion bombardment of the surface at which the elastic waves propagate.</p> |
