Electrohydrodynamic Patterning of Thin Polymer Film

Wu N., Pease III L.F., Russel W.B., Princeton University, US

A polymer melt sandwiched with a gap fluid between two planner electrodes can self assemble into ordered microstructures under the influence of an electric field. Motivated by the variety of patterns observed in experiments, we [...]

Thin Film Instability and Nanostructure Formation: a Molecular Dynamics Study

Han M., Lee J.S., Park S., Choi Y.K., Seoul National University, KR

One of the recent studies showed that the structures can be self-constructed by controlling the instability of thin fluid film of a nano-scale [S.Y. Chou and L. Zhuang, , J. Vac. Sci. and Technol. B, [...]

Multiple Solutions in Electrostatic MEMS

Pelesko J.A., Georgia Institute of Technology, US

The pull-in voltage instability is the principle phenomena limiting the design of nearly every electrostatically actuated MEMS device. In this instability, when applied voltages are increased beyond a certain critical voltage there is no longer [...]

Nonlocal Problems in MEMS Device Control

Pelesko J.A., Triolo A.A., Georgia Institute of Technology, US

Perhaps the most ubiquitous phenomena associated with electrostatically actuated MEMS devices is the "pull-in" voltage instability. In this instability, when applied voltages are increased beyond a certain critical voltage there is no longer a steady-state [...]
