Electromechanical response of high frequency silicon nanowire resonators:simulation and measurements

Koumela A., Mercier D., Marcoux C., Purcell S.T., Hentz S., Duraffourg L., CEA-LETI, FR

Electromechanical models of nano-electromechanical devices are usually implemented with specifically developed mathematical software and these models are not easily compatible with circuit simulation software. However, in order to use a nano-device as a sensor, a [...]

Sensitive detection of nonlinear nanomechanical motion using capacitive signal down-mixing for resonant NEMS-based sensors

Kacem N., Sworowski M., Hentz S., Baguet S., Dufour R., FEMTO-ST, FR

Nanoelectromechanical systems (NEMS) are emerging as strong candidates for a host of important applications in semiconductor-based technology and fundamental science. At this level of miniaturization, the electric characterization of capacitive NEMS is a challenge. In [...]

Design of a nano-mechanical beam based memory element

Sahoo H.K., Uppala A., Anjur R., University of Pennsylvania, US

A cantilever beam based memory element is proposed which can trap static charge on a metal plate on the beam. The charge is tunneled to the metal plate from an electrode separated from it by [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

SiCN nanomechanical resonators for array-based biosensor applications

Guthy C., Singh A., Tanha J., Evoy S., University of Alberta, CA

Rapid, sensitive and inexpensive analysis of biological molecules is of great importance to many biomedical applications, such as disease detection and monitoring, drug discovery, detection of pathogens, etc. Mechanical resonators have been demonstrated as highly [...]

Carbon-based Nanoelectronic Devices for Space Applicatoins

Kaul A.B., Khan A.R., Megerian K.G., von Allmen P., Bagge L., Epp L., Baron R.L., Jet Propulsion Laboratory, US

The microelectronics industry based on Silicon (Si) continues to push the limits on scaling, which has created unique opportunities for nanoscale materials, such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs). We will describe our [...]

Design and Fabrication of Electromechanical Tweezers based on CNT Ropes

RAslan A., Basrour S., Le Poche H., CEA-LETI,Minatec, FR

The aim of this work is to design and fabricate electromechanical tweezers based on CNT ropes. The electromechanical behaviour of such ropes has been studied. The average of Young’s modulus of the rope has been [...]

The Study of Mechanical Stress in NEMS Heterostructures

Xu X., Bogdan B., Lime F., Grenoble institute of technology, FR

Mechanical stress is increasingly applied in microelectronics. For instance, strained silicon technology is widely used to improve carrier mobility and driver current for advanced MOS transistors. For micro-electromechanical systems, piezoresistive effects are widely used in [...]

Control of NEMS Based on Carbon Nanotube

Ershova O.V., Knizhnik A.A., Lebedeva I.V., Lozovik Yu.E., Popov A.M., Potapkin B.V., Kintech Lab Ltd, RU

Here we consider the controlled operation of a gigahertz oscillator based on a carbon nanotube. A new method for controlling the motion of nanoelectromechanical systems (NEMS) is proposed. This method is based on the appearance [...]
