Nanoelectromechanical system

From a reaction engineering viewpoint, semiconductor device fabrication is a sequence of semibatch reactions interspersed with mass transfer steps such as polymer dissolution and physical vapor deposition (e.g., vacuum metallizing and sputtering). Similar sequences are used to manufacture still experimental devices known as NEMS (for nanoelectromechanical systems). 

Recent progress in nanofabrication has shown that SW-CNTs have become an essential building block for nanoelectromechanical systems (NEMSs) and... 

Recently, a great interest appeared in nanoelectromechanical systems (NEMS), which convert electrical current into mechanical motion on a nanoscale and vice versa. The ultimate goal of the NEMS research is development of commercial applications like sensors and actuators at a nanoscale. Currently, the fundamental side of NEMS is being extensively explored, with new physical phenomena being revealed. 

Mechanically interlocked molecules, such as bistable catenanes [13] and [2]rotax-anes [14], constitute some of the most appropriate candidates to serve as nanoscale switches and machines in the rapidly developing fields of nanoelectronics [15] and nanoelectromechanical systems (NEMS) [16]. The advantages of using mechanically interlocked molecules in the fields of molecular electronics and...

New method to control the motion of carbon nanotube-based nanoelectromechanical systems is proposed. Chemosorption of atoms and molecules on open edges of a single-walled carbon nanotube leads to the appearance of electric dipole moment. In this case the nanotube can be actuated by non-uniform electric field. Electric dipole moments of the carbon nanotubes with functionalized edges are calculated. The method proposed is demonstrated with an example of gigahertz oscillator. 

Continued advances in silicon nanoelectronics and beyond will enable developments in adaptive and reconfigurable devices. To enable energy-efficient operation, low-power and low-noise electronics are needed for novel network architectures and advanced systems that incorporate novel nanoelectromechanical systems (NEMS), nanosensors, and nanoactuators. 

D machining of electrochemically active materials, including the construction of unconventional island patterns on a surface with nanoscale resolution, was also realized by this method [95, 115-117]. Thus, electrochemical machining can be applied to microelectromechanical systems (MEMS] [118] and even in the nanoelectromechanical systems (NEMS]. Electrochemical methods can realize the nanofabrication in a selective place and make the complicated 3D nanostructures. Conducting polymers can also be fabricated in this way. Similar to the electrochemical machining, by application of short voltage pulses to the tool electrode in the vicinity of the workpiece electrode, the electropolymerization... 

In recent years, micro/nanoelectromechanical systems (M/NEMS) have been rapidly developed for important applications in navigation, space flight, and industry [2]. The characteristics of microscale gas flows differ from those of macroscale flows. Eor example, at normal temperatures...
