Abstract
Lithium tetraborate (Li2B4O7) has attracted much attention as a surface acoustic wave substrate for high-frequency use and its excellent nonlinear optical properties have been recently found. In the present report, the main crystalline defects observed by X-ray topography in Li2B4O7 (110) wafers grown by the Bridgman method and by the Czochralski method are presented. The main trends observed are a majority of dislocations in {112} planes, a minority of dislocations in the {111} planes, and low-angle grain boundaries in both {111} and {112} planes.
