摘 要:探讨了外界激振对扫描探针显微镜 (SPM)图像的影响。针对DI扫描探针显微镜MultiModeTM SPM ,以Tektronix任意波形发生器AWG2 0 2 1驱动PC扬声器作为激振源 ,以SIOS微型激光干涉测振仪SP S为测振系统 ,研究了 0~ 7kHz频带内SPM机体的简谐迫振对扫描图像的影响。实验表明 ,针尖 -样品副所受激振影响不同于SPM机体 ;0~ 1kHz频带内的激振影响显著 ,再高频段则影响甚微 ;外界激振与SPM扫描的综合作用影响成像的结果 ;针尖This article was concentrated on the influence of external vibration on scanneing images of scanning probe microscope (SPM). The object studied was a DI MultiMode TM SPM. The external vibrating source was a PC speaker driven by a Tektronix ambient waveform generator AWG2021. A SIOS miniature interferometric vibrometer SP S was used as vibration measuring system. The influence of 0~7kHz harmonic vibration of SPM base on the scanning images was studied. The results of experiments were concluded as: external vibration influence on SPM base was different from the one on tip sample interaction; great influence of the external vibration appeared in 0~1kHz, and weak at higher frequency ranges; SPM image was influenced by the combination of external vibration and scanning rate; viscoelastic model of the tip sample interaction theory should be used to study the vibration influence on SPM.
关 键 词:扫描探针显微镜 SPM图像 扫描速率 外界激振 粘弹性模型 扫描频率 固有频率 针尖-样品副
