【摘要】 在扫描探针显微镜 (SPM)的扫描过程中 ,由SPM的扫描线与物质表面周期性晶格结构进行干涉可以形成纳米云纹图像 .采用高取向热解石墨 (HOPG)和云母作为试件 ,分别对扫描隧道显微镜 (STM)和原子力显微镜 (AFM)云纹进行了研究 ,实验结果与理论分析完全一致 .SPM纳米云纹法在纳米测量和表征方面具有较大的应用前景 .更多还原

【Abstract】 A Moiré technique using a scanning probe microscope (SPM) is developed, in whic h the natural periodic structure of a crystal is used as an ideal spacing gratin g. Formation principle of the SPM moiré fringes is discussed. Moiré patterns f ormed on highly oriented pyrolytic graphite (HOPG) and mica are investigated exp erimentally with STM and AFM, respectively. The results demonstrate the feasibil ity of the SPM Moiré technique in studying deformation and defects of crystals at the nanometer scale.更多还原
