A combination of capillary and dielectrophoresis-driven assembly methods for wafer scale integration of carbon-nanotube-based nanocarpets [PDF]
, 2012 The wafer scale integration of carbon nanotubes (CNT) remains a challenge for electronic and electromechanical applications. We propose a novel CNT integration process relying on the combination of controlled capillary assembly and buried electrode ...

Carbon nanotube based 3-D matrix for enabling three-dimensional nano-magneto-electronics [corrected]. [PDF]
PLoS ONE, 2012 This letter describes the use of vertically aligned carbon nanotubes (CNT)-based arrays with estimated 2-nm thick cobalt (Co) nanoparticles deposited inside individual tubes to unravel the possibility of using the unique templates for ultra-high-density ...

Carbon nanotube array vias for interconnect applications [PDF]
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2009 The purpose of this study is to investigate the effect of carbon nanotube (CNT) growth parameters on CNT via resistance and examine the transverse motion of electrons in the CNT bundle vias. Single vias of 3.85×3.85 and 2.45×2.45μm2 correspond to 0.35×0.35μm2 6×6 and 4×4 array vias, respectively.

Unidirectional and bi-directional growth of carbon nanotubes on the catalytic Co–Zr–N-(O) material
Journal of Materials Research and Technology, 2021 In this paper we have demonstrated the possibility of the MWCNT growth on initially amorphous Co–Zr–N–O alloy thin film which was crystallized during heating followed by formation of Co particles on the surface.

Aligned Graphene Nanoribbons and Crossbars from Unzipped Carbon Nanotubes [PDF]
, 2010 Aligned graphene nanoribbon (GNR) arrays were made by unzipping of aligned single-walled and few-walled carbon nanotube (CNT) arrays. Nanotube unzipping was achieved by a polymer-protected Ar plasma etching method, and the resulting nanoribbon array was ...

Sliding on carbon nanotube arrays
Philosophical Magazine Letters, 2008 Adhesion, friction and wear of Single-Walled Nanotube (SWNT) and multi-walled nanotube arrays have been investigated. SWNT arrays exhibit lower adhesion and friction values on account of the lower van der Waals’ forces resulting from lower packing density and higher flexibility. Wear tests show that both arrays do not wear.

Beilstein Journal of Nanotechnology, 2017 In this work we modelled the diffusive transport of a dilute gas along arrays of randomly distributed, vertically aligned nanocylinders (nanotubes or nanowires) as opposed to gas diffusion in long pores, which is described by the well-known Knudsen ...

Journal of Advanced Materials in Engineering, 2021 Carbon nanotubes contain impurities and deamorphization is one of the methods of their purification. In this study, for the first time, a solution of piranha with a ratio of 3:1 (30 ml sulfuric acid + 10 ml hydrogen peroxide) as well as microwave ...
