Michael J. Biercuk, Joseph W. Britton, Hermann Uys, Aaron Vandevender, John Bollinger
Recent experimental advances have shown that it is possible to detect forces arising from electric fields at a level of aN/ √Hz (atto = 10 -18 through coupling

AFM characterization of nanopositioner in-plane stiffnesses

Author(s)
Seung Ho Yang, Yong Sik Kim, Premsagar P. Kavuri, Jae M. Yoo, Young M. Choi, Nicholas G. Dagalakis
A versatile method for measurement of in-plane stiffness of micro-elements was developed and its usefulness has been demonstrated. The in-plane stiffness of a
