Inelastic Transport in Carbon Nanotube Electronic and Optoelectronic Devices
28 Jun 2013 | | Contributor(s):: Siyu Koswatta
Discovered in the early 1990's, carbon nanotubes (CNTs) are found to have exceptional physical characteristics compared to conventional semiconductor materials, with much potential for devices surpassing the performance of present-day electronics. Semiconducting CNTs have large carrier...
Optical Absorption in B13 Cluster: A Time-dependent Density Functional Approach
19 Feb 2013 | | Contributor(s):: Ravindra L Shinde, Meenakshi Tayade
The linear optical absorption spectra of three isomers of planar boron cluster B13 are calculated using time dependent spin-polarized density functional approach. The geometries of these cluster are optimized at the B3LYP/6-311+G* level of theory. Even though the isomers are almost degenerate,...
