Molecular Dynamics Study of Electromechanical Nanotube Random Access Memory

Kwon O-K., Kang J-W, Byun K.R., Lee J-H., Hwang H-J., 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 [...]

Counting and Controlling Point Defects in Carbon Nanotube Electronic Circuits

Fan Y., Emmott N., Collins P.G., University of California Irvine, US

As with any disruptive technology in its early stages, nanoelectronics faces major scientific and technological challenges. As initial investigations of carbon nanotube circuits mature, attention can be turned to issues of reliability and reproducibility. This [...]

An Innovative Ignition Method using SWCNTs and a Camera Flash

Danczyk S., Chehroudi B., ERC/ Air Force Research Laboratory, US

It was reported in the literature that as-produced single-walled carbon nanotubes (SWCNTs) ignited when accidentally subjected to a common photographic flash at a close range. This effect was observed for dry and “fluffy” SWCNTs but [...]

Computing Encapsulation of Non-metallic Molecules: N2@C60

Slanina Z., Nagase S., Institute for Molecular Science, JP

Recent observation of N2@C60 is supported computationally. The geometry is optimized at the B3LYP/3-21G and PW91/3-21G levels. The lowest-energy structure has the N2 unit oriented towards a pair of parallel pentagons so that the complex [...]

The Structure and Properties of ta-C Film with Dispersion of Incident Beam Energy

Lee K-R, Lee S-C, Lee S-H., Kim T.-Y., Lee K-R, Lee S-C, Lee S-H., Chung Y-C, Brenner D.W., Lee K-R, Lee S-C, Lee S-H., Korea Institute of Science and Technology, KR

We investigated the structural properties of ta-C film as a function of the dispersion in the incident kinetic energy. The ta-C films were produced on a diamond (100) surface by the bombardment of 3, 000 [...]

Hybrid Nanomaterials for Active Electronics and Bio-Nanotechnology

Wang X., Pandey R.R., Lake R., Ozkan C.S., University of California Riverside, US

We describe self assembly processing of functional carbon nanotubes using single strand deoxyribonucleic acid (DNA) and peptide nucleic acid (PNA) fragments. Previous research has shown the self assembly of carbon nanotubes to quantum dots via [...]

Structural Study of Amorphous Carbon using Adaptive Interatomic Reactive Empirical Bond-order Potential Model

Knippenberg M.T., Kum O., Stuart S.J., Clemson University, US

We studied the structural properties of amorphous carbon covering a wide range of densities from low-density to high-density regime using classical molecular dynamics with reactive empirical bond-order potential model. We calculated the pair-correlation functions, relative [...]
