Journal ArticleDOI
Super-elasticity of three-dimensionally cross-linked graphene materials all the way to deep cryogenic temperatures.
Kai Zhao,Tengfei Zhang,Huicong Chang,Yang Yang,Peishuang Xiao,Hongtao Zhang,Chenxi Li,Chandra Sekhar Tiwary,Pulickel M. Ajayan,Yongsheng Chen +9 more
TL;DR: Wide temperature–invariant large-strain super-elastic behavior in three-dimensionally cross-linked graphene materials that persists even to a liquid helium temperature of 4 K is reported, a property not previously observed for any other material.
Journal ArticleDOI
Charge distribution and stability of charged carbon nanotubes.
TL;DR: Density-functional calculations of charge distribution on negatively and positively charged nanotubes result in charge density profiles characterized by a significant increase of charge density at the tube ends, in quantitative agreement with classical electrostatic analysis.
Journal ArticleDOI
Resistance of copper nanowires and comparison with carbon nanotube bundles for interconnect applications using first principles calculations
TL;DR: In this paper, the electronic properties and the band structure of copper nanowires for various diameters using first principles density functional methods and a supercell approach were studied and compared with those obtained from an empirical approach.
Journal ArticleDOI
Charge-injection-induced dynamic screening and origin of hysteresis in field-modulated transport in single-wall carbon nanotubes
Aravind Vijayaraghavan,Swastik Kar,Caterina Soldano,Saikat Talapatra,Omkaram Nalamasu,Pulickel M. Ajayan +5 more
TL;DR: In this paper, the authors experimentally established this alternative mechanism, in which the screening charges are injected from the nanotube itself into the surrounding dielectric, and all experimental results can be simply explained in terms of a capacitive charging of the surrounding.
Journal ArticleDOI
