化学力显微镜 (CFM)
CFM测量化学相互作用
CFM measures the chemical interactions between functionalized tips and sample to determine the chemical nature of surfaces and facilitate studies of chemical bonding enthalpy and surface energy. Tips are typically gold-coated and functionalized with R-SH thiols, R being the functional groups of interest such as -CH, -COOH, -NH, and -OH.
