Eigenmodes of a quartz tuning fork and their application to photo-induced force microscopy
Bongsu Kim, Junghoon Jahng, Ryan Muhammad Khan +2
We examine the mechanical eigenmodes of a quartz tuning fork (QTF) for the purpose of facilitat- ing its use as a probe for multi-frequency atomic force microscopy (AFM). We perfor…
