Popis:	Defects in lithium tetraborate Li/sub 2/B/sub 4/O/sub 7/ (LBO) and their influence on performance of devices are concerned by crystal material researchers and device engineers with production of 3-inch diameter LBO crystal by the Bridgman (BR) technique and application and design of surface acoustic wave (SAW) devices fabricated on LBO substrate. The defects in the BR-grown LBO of 3-inch diameter are observed by chemical etching and microscopy. The main defects in the crystal are sub-grain boundaries and dislocations. Growth striation, scattering particle and twin occur in the crystal occasionally. The configuration of the defects, their origins and preventive methods are also described. >
