Strong, controllable, robust, and scalable graphene n-doping for optoelectronic and micro/nano-electronic applications

Folkson J., Ashraf A., Eisaman M.D., Stony Brook University(SBU)/Brookhaven National Lab(BNL), US

Graphene holds promise for many applications such as microelectronics, optoelectronics, and energy storage due to its outstanding properties. The realization of these applications, however, requires tailoring graphene’s electronic properties via controlled doping (addition or removal [...]

The selectivity features of a biological functionalized carbon nanotubes complex towards blood

Cortes P., Fagan D., Olszewki A., Radetic M., Abdallah G., Youngstown State University, US

The present work has studied the selectivity process of a biological complex based on Carbon Nanotubes and a specific amino-acid sequence for interacting specifically with blood. In this work, Human Serum Albumin (HSA) has been [...]

Characterization of electrical property and band-structure in carbon nanotube/GaN hetero-interface

Yokogawa T., Miyake S., Yamashita A., Yamaguchi University, JP

Recently power devices using GaN have attracted much attention because of high power and high efficiency due to the wide band-gap. These power devices are generally used in high temperature operation by the heat dissipation [...]

Adsorption of Cl adatom on Na-Decorated graphene

Yuan G., Song X., Li C., Wang J., Mimura H., Ocean University of China, CN

In this presentation, the effects of the Cl adatom on Na-decorated graphene are studied using first principles density functional theory. The adsorption energy, geometric structure, charge density difference, and density of states are calculated under [...]

Development of “thermoelectric power generating paper” using carbon-nanotube-composite paper

Kawata K., Oya T., Graduate School of Engineering, Yokohama National University, JP

We propose an unique thermoelectric material based on a carbon-nanotube(CNT)-composite paper[1] that a composite material of the CNT and a paper, i.e., a “thermoelectric power generating paper.” In recent years, about two thirds of the [...]

SWCNT TUBALL as a universal conductive additive in plastics

Ilin E.S., Bezrodny A.E., Predtechenskiy M.R., OCSiAl LLC (OCSiAl Group), US

The development of electro-conductive plastics filled with SWCNTs is demonstrated. A number of different plastics filled with TUBALLTM such as polyethylene, polypropylene, ABS-plastic, polystyrene etc. exhibit electrical resistance in the range of 10^8-10^4 Ω*cm. The [...]

The Brain-Machine Interface: Nanotechniques for Improving Brain Electrochemical Monitoring and Modulating

Andrews R., Bennet K., Chang S.Y., Koehne J., Lee K., Meyyappan M., Rand E., NASA Ames Research Center, US

Purpose: Present-day neuromodulation, e.g. deep brain stimulation (DBS), is limited by inefficient charge transfer from electrodes to brain tissue, lack of brain chemical (neurotransmitter) monitoring, and absence of feedback-guided stimulation. Although DBS using platinum macroelectrodes [...]

Carbon Nanotube Silicon Heterojunction Solar Cells

Yu L., Tune D., Shapter J., Flinders University, AU

Due to the high cost of silicon photovoltaics there is currently great interest in finding alternative semiconductor materials for light harvesting devices. Single walled carbon nanotubes (SWCNTs) are an allotrope of carbon having unique electrical [...]

Integration of graphene into nanoelectronic devices: insights from atomistic simulations

Garcia M., Artacho E., Simune Atomistics S.L., ES

A deep knowledge on the electronic properties of graphene derivatives is critical to successful integration of graphene into future nanoelectronic devices. We investigate the electronic properties of graphene upon adsorption of gases expected to be [...]
