Graphene Nanostructures : A Theoretical Study Of Electronic, Magnetic And Structural Properties
(2014-09-26)
Graphene is a single layer of carbon atoms arranged in honeycomb lattice. Over a long period of time it was treated as a hypothetical material to understand the properties of other allotropes of carbon, such as graphite, ...
From Synthesis To Applications Of Pristine And Nitrogen-Doped Carbon Nanotubes
(2015-07-13)
Carbon nanotubes (CNTs) are well known as excellent electrical conductors. However, their transport properties are limited by electrical breakdown in ambient. Moreover, the electronic properties can further be modulated ...
