Single Walled Carbon Nanotubes based Three Dimensional Flexible Electronics

Makaram P., Selvarasah S., Chen C., Busnaina A., Dokmeci M.R., Northeastern University, US

Single Walled Carbon Nanotubes (SWNTs) with their superior electrical and mechanical properties are very strong candidates for future electronic applications. CMOS electronics are constantly being scaled down to accommodate more devices. Alternative device geometries are [...]

Continuum Modeling the Behavior of Carbon Nanotubes in different load condition

Chaboki A., Sadrnejad S.A., Yahyaiee M., University of Sydney, AU

Molecular dynamics and quantum mechanics are the best method for analysis the CNTs behavior. Bur because of the difficulties and cost, this task is limited to small structure with limited atoms number. In this paper, [...]

Modelling the Stress Transfer in CNT Composite using Finite Element Method

Chaboki A., Sadrnejad S.A., Yahyaeii M., University of Sydney, AU

Since carbon nanotubes have special mechanical properties, they tend to be used as reinforcements in composites. The stress transfer between the nanotubes and the matrix at the interface critically controls the mechanical properties of these [...]

Studies of Nanotube-based Co-axial and Resonant Oscillators

Xiao S.P., Andersen D., Hou W.Y., The University of Iowa, US

In this paper, we first investigate mechanisms of nanotube-based co-axial oscillators, shown in Figure 1, based on molecular dynamics simulation. We mainly study the interlayer friction between the outer tube and the inner tube when [...]

A Sensitive Peptide-Nanotube Based Pathogen Assay

MacCuspie R.I., Banerjee I.A., Gummalla S., Mostowski H., Krause P., Matsui H., Hunter College, US

A novel peptide nanotube-based multiplexed pathogen assay has been developed that has high sensitivity, detecting as few as 100 pathogens per mL in as little as 0.5mL. Multifunctional nanotubes detect viruses by selectively binding antibody [...]

Using Ultra-long Nanotubes to Make Identical CNT FETs

Yu Z., Rutherglen C., Li S., Burke P.J., University of California Irvine, US

Centimeter scale aligned carbon nanotube arrays are grown from nanoparticle/metal catalyst pads. We find the nanotubes grow both with and “against the wind”. A metal underlayer provides in-situ electrical contact to these long nanotubes with [...]

Fabrication of Metal Oxide Coaxial Nanotubes using Atomic Layer Deposition

Jeong D-K, Oh T-K, Shin H-J, Jung W.-G., Lee J-G, Sung M-M, Kim J-Y, Kookmin University, KR

We fabricated of nanotubular structures of TiO2 and ZrO2 using the gas-phase fabrication method atomic layer deposition (ALD) with nanoporous structure of polycarbonate (PC) templates. Contact printed alkylsiloxane monolayers on both sides of PCs were [...]

A Nanoelectronic Device Based on Endofullerene Peapod: Model Schematics and Molecular Dynamics Study

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

We investigated a nanoelectronic device based on multi endo-fullerenes shuttle memory element based on nanopeapods using classical molecular dynamics simulations. We suggested the model schematics of endo-fullerene shuttle memory device fabrication. The dynamics of the [...]

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 [...]

Experimental Observation of Carbon and Carbon-Metal Nanotoroids and New Carbon-Metal Superstructures at Nanoscale

Kislov V., Medvedev B., Taranov I., Russian Academy of Sciences, RU

We report experimental observation (by AFM, STM and HRTEM methods) of nanotoroids for both carbon and carbon-metal superstructures produced by methods of arc discharge and laser ablation. Size of superstructures is ~ 10 nm for [...]
