Strong and stable photoluminescence from the semiconducting inner tubes within double walled carbon nanotubes
(2009-01)
"We examined the optical features of single wall carbon nanotubes (SWNTs) and the inner tubes within double walled carbon nanotubes (DWNTs) having the same (n,m) chirality. The brighter and more stable photoluminescence ...
Diameter-selective separation of double-walled carbon nanotubes
(2008-12)
"Here, we report a simple and effective way of separating double-walled carbon nanotubes as a function of their diameter using individually dispersed nanotube solutions with the aid of long and random single-stranded DNA. ...
CdSe quantum dot-decorated double walled carbon nanotubes: the effect of chemical moieties
(2008-08)
"We report that fluorine atoms on the outer tubes of double walled carbon nanotubes (DWNTs) are more effective for nucleating and growing CdSe nanoparticles than oxygen-containing functional groups. The CdSe particles with ...
Design of graphene electronic devices using nanoribbons of different widths
(2009-10)
"We present a simple design of a field effect transistor based on graphene nanoribbons, taking advantage of the metallic and semiconductor nature of nanoribbons with different widths. Such device could be constructed by ...
Generalizing segregation and chemical ordering in bimetallic nanoclusters through atomistic view points
(2009-10)
"We predict general trends for surface segregation in binary metal clusters based on the difference between the atomic properties of the constituent elements. The energetically most favorable site for a guest atom on a ...
New direction in nanotube science
(Elsevier, 2004)
"We review the latest advances in the production and state-of-the art characterization of B- and N-doped carbon nanotubes (CNTs) and nanofibers. We briefly discuss different approaches to producing these novel doped ...
Transport and diffusion on crystalline surfaces under external forces
(IOP Publishing, 2005)
"We present a numerical study of classical particles obeying a Langevin
equation and moving on a solid crystalline surface under an external force that
may either be constant or modulated by periodic oscillations. We focus ...
Stationary states in a potential well
(UNESCO, 2007)
"In the early days of the 20th century a set of important observations in atomic and molecular physics could not be explained on the basis of the laws of classical physics. One of the main findings was the emission of light ...
Magnetic properties of Fe nanoclusters: ab initio calculations of FeN N = 9,15, 27, 51, and 59
(Sociedad Mexicana de Física, A. C., 2006)
"The magnetic properties of iron clusters (FeN, N = 9, 15, 27, 51, and 59 atoms) at T = 0 K with bcc–like structure and bulk parameters are studied using ab initio methods. In these studies we consider the spin–orbit ...
