Thermal and Electromagnetic Effects on Cantilevers at Nanometer Length Scales
Abstract
As the size of mechanical, electrical, and optical devices continues to be reduced, forces due to thermal and electromagnetic interactions become increasingly relevant. An increasing number of micro- and nano-sized devices utilize cantilevers. At such small length scales coupling to the external environment may dominate the behavior of the system. In this study, cantilever dynamics near fixed surfaces under ambient conditions are investigated. A system of Langevin type equations with weak colored noise coupled through the electromagnetic interaction is used and compared with experimental data. Within the realms of this model, limits on the geometry and dimensions of cantilever-based devices are studied.
