Photo-excitation of a light-harvesting supra-molecular triad: a Time-Dependent DFT study
N. Spallanzani, C. A. Rozzi, D. Varsano +4
We present the first time-dependent density-functional theory (TDDFT) calculation on a light harvesting triad carotenoid-diaryl-porphyrin-C60. Besides the numerical challenge that…
Nanoparticle networks as chemoselective sensing devices
Natalya A. Zimbovskaya, Mark R. Pederson, Amy S. Blum +2
We theoretically analyzed transport properties of a molecular network constructed of gold nanoparticles linked with oligophenylenevinulene (OPV) molecules. We showed that the condu…
Negative differential resistance in molecular junctions: The effect of the electrodes electronic structure
Natalya A. Zimbovskaya, Mark R. Pederson
We have carried out calculations of electron transport through a metal-molecule-metal junction with metal nanoclusters taking the part of electrodes. We show that negative differen…
The vibrational stability and electronic structure of B80 fullerene-like cage
Tunna Baruah, Mark R. Pederson, Rajendra R. Zope
We investigate the vibrational stability and the electronic structure of the proposed icosahedral fullerene-like cage structure of B80 [Szwacki, Sadrzadeh, and Yakobson, Phys. Rev.…
Static dielectric response of icosahedral fullerenes from C60 to C2160 by an all electron density functional theory
Rajendra R. Zope, Tunna Baruah, Mark R. Pederson +1
The static dielectric response of C60, C180, C240, C540, C720, C960, C1500, and C2160 fullerenes is characterized by an all-electron density-functional method. First, the screened…
Polarizabilities of Intermediate Sized Lithium Clusters From Density-Functional Theory
Rajendra R. Zope, Tunna Baruah, Mark R. Pederson
We present a detailed investigation of static dipole polarizability of lithium clusters containing up to 22 atoms. We first build a database of lithium clusters by optimizing sever…
