Dynamic surface roughening and the Casimir force in MEMS/NEMS

Joint PhD student: Peter van Zwol
The aim of the proposed research is to scrutinize the influence of random roughness and its dynamic scaling on the Casimir effect, which arise from the perturbation by conducting plates of zero point vacuum fluctuations of the electromagnetic field. When the proximity between material objects becomes of the order of several nanometers, a regime is entered in which dispersive surface forces that are quantum mechanical in nature, namely, van der Waals (for separations> 10 nm) become operative (joint efforts with dr. G. Palasantzas).
