Determination of the lowest energy structure of Ag8 from first-principles calculations
نویسندگان
چکیده
The ground-state electronic and structural properties, and the electronic excitations of the lowest energy isomers of the Ag8 cluster are calculated using density functional theory (DFT) and timedependent DFT (TDDFT) in real time and real space scheme, respectively. The optical spectra provided by TDDFT predict that the D2d dodecahedron isomer is the structural minimum of Ag8 cluster. Indeed, it is borne out by the experimental findings.

We report a joint experimental and theoretical study of two luminescent molecular quantum clusters of silver, Ag7(H2MSA)7 and Ag8(H2MSA)8 (H2MSA is the dicarboxylic acid of mercaptosuccinic acid in thiolate form). Global optimizations and property calculations are performed in the framework of density-functional theory (DFT-PBE) to search for the leading candidates with the lowest energy. The s...

Graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. Structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (LDA). Band structures and density of states for the propose carbon 3D models are reported. A finite energy gap and...
