提出了一种在室温下利用调频原子力显微镜进行可重复的定点力谱测量的方法。的稳定性和再现性的要求，满足到目前为止，只有在低温环境中，通过使用原子跟踪技术的热漂移的补偿。该方法已被测试执行光谱测量的Si（111）-（7 × 7）表面的原子位置与Si尖。在这里提出的室温结果比较质量，以前报道的定量力谱数据在低温下获得。(C)2005年美国物理学会。
A method for reproducible site-specific force spectroscopic measurements using frequency modulation atomic force microscopy at room temperature is presented. The stability and reproducibility requirements, fulfilled so far only in cryogenic environment, are provided through the compensation of the thermal drift using the atom-tracking technique. The method has been tested performing spectroscopic measurements on atomic positions of the Si(111)-(7x7) surface with Si tips. The room-temperature results presented here compare in quality to previously reported quantitative force spectroscopic data obtained at cryogenic temperatures. (C) 2005 American Institute of Physics.
