摘要

X-ray diffraction topography can easily detect and image the presence of defects within a crystal, making it a powerful nondestructive evaluation tool for characterizing industrially important single crystal specimens such as quartz. Whether looking for gross defects (crystallographic misorientations) or smaller defects such as dislocations or even atomic (point defect) scale influences, the x-ray diffraction topographic techniques are well suited to a variety of applications. In the examples shown, x-ray topography was utilized to distinguish between "good" and "bad" resonators and evaluate the crystalline perfection of cultured, raw quartz samples produced in a new seeded crystal growth orientation. Further use of x-ray diffraction topography would aid in the optimization of such crystal growth and processing of quartz as well as other single crystal applications.
