We report on the first single- and few-layer molybdenum disulfide (MoS2) nanoelectromechanical resonators with local electrical gate, and the demonstration of local-gate all-electrical actuation, detection, and tuning of the atomic-layer MoS2 resonators at very high frequency (VHF). These local-gate structures make MoS2 vibrating-channel transistors (VCTs), and facilitate efficient frequency modulation...
Rescue and salvage works are often carried out under the sea in harsh conditions. The position and attitude of under platforms may change at any time by ocean currents, thus produces great difficulties for underwater search and fixed-point rescue. This paper aims to realize the efficient control of underwater platform attitude and effectively improve the operation efficiency of underwater platforms...
We demonstrate nanoelectromechanical contact-mode switches and logic gates with high performance, enabled by cantilever-structured SiC nanoelectromechanical systems (NEMS). In full-cycle recording measurements (complete time-domain trace of every single switching cycle recorded), we show that in ambient air, SiC NEMS switches with nanocontacts have operated >1×107 cycles of ‘hot-switching’ without...
We present demonstration and experimental results of four-terminal nanoscale electromechanical switches with a novel dual-gate design in a lateral configuration based on polycrystalline silicon carbide (poly-SiC) nanocantilevers. The switches operate at both room temperature and high temperature up to T≈500°C in ambient air with enhanced control over the distributed electrostatic actuation force,...
We report experimental demonstration of nanoscale electromechanical contact-mode switches with clearly high comparative performance, enabled by polycrystalline silicon carbide (poly-SiC) nanomechanical cantilevers, in a three-terminal, gate-controlled, lateral configuration. We have recorded the complete time evolution of the measured switching events in ambient air, by switching devices on and off...
This digest paper reports experimental demonstration of a new type of nanoelectromechanical device, combining contact-mode nanomechanical switching with sensitive integrated strain gauges in suspended thin (sub-100nm) silicon nanowires (SiNWs). By measuring and modeling the interesting coupling effects between mechanical strain and electrical transport in highly piezoresistive (PZR) thin SiNWs at...
