Na.iona. Science Review 2024年第7期11卷 64-65页

作者： eric O.Potma Depa.tment of Chemistry University of California

In sca.ning probe microscopy(SPM),a.sha.p tip sca.s a.ross a.sa.ple to produce a. ima.e with na.ometer-sca.e resolution or better. SPM contra.t is derived from the physica. interpla. between the tip a.d the sa.ple. a.specia. cla.s of SPM techniques mea.ures forces when the tip–sa.ple junction is illumina.ed by a. externa. light source. Photo-induced forces ca. be sensitive to the optica. properties of the sa.ple, thus ena.ling na.osca.e ima.ing with spectroscopic,ma.eria.-specific contra.t.
