Parametric amplification in single-walled carbon nanotube nanoelectromechanical resonators
The low quality factor (Q) of single-walled carbon nanotube (SWNT) resonators has limited their sensitivity in sensing application. To this end, we employ the technique of parametric amplification by modulating the spring constant of SWNT resonators at twice the resonant frequency and achieve 10 times Q enhancement. The highest Q obtained at room temperature is around 700, which is 3–4 times be...
متن کاملCapacitive spring softening in single-walled carbon nanotube nanoelectromechanical resonators.
We report the capacitive spring softening effect observed in single-walled carbon nanotube (SWNT) nanoelectromechanical (NEM) resonators. The nanotube resonators adopt a dual-gate configuration with both bottom-gate and end-gate capable of tuning the resonance frequency through capacitive coupling. Interestingly, downward resonance frequency shifting is observed with increasing end-gate voltage...
متن کاملSingle-Walled Carbon Nanotube Electronics
Single walled carbon nanotubes (SWNTs) have emerged as a very promising new class of electronic materials. The fabrication and electronic properties of devices based on individual SWNTs are reviewed. Both metallic and semiconducting SWNTs are found to possess electrical characteristics that compare favorably to the best electronic materials available. Manufacturability issues, however, remain a...
متن کاملSingle - Walled 14 . Single - Walled Carbon Nanotube Sensor Concepts
Carbon nanotubes are nanocomponents par excellence that offer unique properties to be exploited in next-generation devices. Sensing applications are perhaps the class that has most to gain from single-walled carbon nanotubes (SWNTs); virtually any property of SWNTs (e.g., electronic, electrical, mechanical, and optical) can result or has already resulted in sensor concept demonstrators. The bas...
متن کاملSingle-Walled Carbon Nanotube Network Gas Sensor
Gas sensors are generally defined as devices to detect or measure concentration of (bio-) chemicals in gaseous state. The demands of highly sensitive gas sensors for industry, environmental monitoring, safety, biomedicine, and pharmaceutics have provoked the intensive research interests in micro-electromechanical systems (MEMS) and nanotechnology. The nanotechnology in conjunction with MEMS has...
