Molecular Dynamics Simulation Study on Nanoelectromechanical Oscillator based on Graphene Nanoflake

Kang J-W, Kwon O-K., Semyung University, KR

Recently graphene has also been highlighted as an ideal lubricant for microelectromechanical systems (MEMSs) and nanoelectromechanical systems (NEMSs), where ‘traditional’ lubricants no longer function normally. Atomic-scale graphene can be fabricated using micro- mechanical chop crack, [...]

Modeling and Simulation on Crossroad-Type Graphene-Resonator Accelerometer

Kang J-W, Kwon O-K., Korea National University of Transportation, KR

Accelerometers have multiple applications in industry and science, and can be used as sensors in a wide variety of devices. Highly sensitive accelerometers are components of inertial navigation systems for both aircraft and missiles, as [...]

Design and Simulation on Nanoelectromechanical bi-layer Graphene Nanoribbon Device with Graphene Nanoflake Shuttle

Kang J-W, Kwon O-K., Lee J-H., Semyung University, KR

Nanoelectromechanical (NEM) switches are similar to conventional semiconductor switches in that they can be used as relays, transistors, logic devices and sensors, and they are promising devices for use in mechanical computing, data storage, and [...]

Bi-Layer Graphene Nanoribbon Memory with Graphene Nanoflake Shuttle

Kang J-W, Kwon O-K., Lee J-H., Semyung University, KR

We investigated the dynamic properties of graphene-nanoribbon (GNR) memory encapsulating graphene-nanoflake (GNF) shuttle in the potential to be applicable as a non-volatile random access memory via molecular dynamics simulations. This work explicitly demonstrates that the [...]

A Molecular Dynamics Modeling on Cantilevered Triple-Walled Carbon Nanotube Resonators

Hwang H-J., Kang J-W, Kwon O-K., Lee J-H., Sangmyung University, KR

We introduce intertube interactions of cantilevered (3,3)(8,8)(13,13) triple-walled carbon nanotube resonators via classical molecular dynamics simulations. The fundamental frequencies of TWCNT resonators were less than those of single- and double-walled carbon nanotubes of a given [...]

Molecular Dynamics Simulations of Nonvolatile Carbon Nanotube Shuttle Memory

Hwang H-J., Kang J-W, Kwon O-K., Lee J-H., Semyung University, KR

We propose a novel carbon-nanotube (CNT)-based nonvolatile memory, which can serve as a key building block for molecular-scale computers and perform molecular dynamics simulations to investigate the dynamic operations of a double-walled CNT memory. We [...]

The Modeling and Characterization of Nano-Scale MOSFET Resistance

Byun K.R., Hwang H-J., Kang E-S, Kang J-W, Kwon O-K., Lee H.J., Lee J-H., Lee J-Y, Lee W.H., Sangmyung University, KR

It has been reported that both the shallow junction and the heavily doped extension as the methods to minimize the off-current and to stabilize the on-current of the sub-90nm scaled device, can solve the short-channel [...]

Molecular Dynamics Study of Electromechanical Nanotube Random Access Memory

Byun K.R., Hwang H-J., Kang J-W, Kwon O-K., Lee J-H., Chung-Ang University, KR

In this work, an electromechanical nanotube random access memory (NRAM) device based on carbon nanotube (CNT) shown in Fig. 1 was investigated using atomistic simulations. The interaction between the CNT-lever and the drain electrode or [...]
