When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

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,...
