Nanoelectromechanical (NEM) switches have emerged as a promising competing technology to the conventional metal-oxide semiconductor (MOS) transistors. NEM switches exhibit abrupt switching behavior with large on-off current ratios, near-zero off-state leakage currents and sub-threshold slopes below the 60 mV/decade theoretical limit of conventional MOS devices [1]. However, current NEM switches commonly...
Utilizing stiction, a common failure mode in micro/nano electromechanical systems (M/NEMS), we propose a method for the controlled fabrication of nanometer-thin gaps between electrodes. In this approach, a single lithography step is used to pattern cantilevers that undergo lateral motion towards opposing stationary electrodes separated by a defined gap. Upon wet developing of the pattern, capillary...
The electrochemical properties of conducting polymers are highly dependent on the microstructure. We report a method to produce specific microstructures of polypyrrole through electro-polymerization in the presence of the amphiphile N-{11-(2-hydroxyethyldimethylammonium)undecanoyl}-N,N′-dioctyl-l-glutamate, bromide, which forms supramolecular hydrogels with pyrrole in aqueous solution. These hydrogels...
