场离子显微镜~FIM！是用来解析在W， Pt和Pt/Ir合金的尖端支撑的单个纳米尺寸的Au团簇的原子结构和取向。来自单个簇的FIM图像表明，该技术能够在超高真空环境中提供支持的纳米尺寸簇的原子分辨率图像。通过比较FIM图像的计算机模拟与实验数据，可以确定支持簇的原子结构和取向。@s0163——1829 ~ 98 !07528 - 6 #
Field-ion microscopy ~FIM! is used to resolve the atomic structure and orientation of individual nanometersize Au clusters supported on sharp tips of W, Pt, and a Pt/Ir alloy. The FIM images from a single cluster illustrate that the technique is capable of providing atomically resolved images of supported nanometer-size clusters in an ultrahigh vacuum environment. By comparing computer simulations of a FIM image to experimental data, the atomic structure and orientation of the supported cluster can be determined. @S0163-1829~98!07528-6#
