METALS AND CHARGE TRANSFER

Charge Transport in Synthetic Metals

The phenomenology of charge transport in synthetic metals is reviewed. It is argued that the conventional quasiparticle picture and Boltzmann transport theory do not apply to these materials. The central ideas of Fermi liquid theory are reviewed, and the significant corrections produced by quasiparticle scattering from ferromagnetic spin fluctuations in liquid He are described. It is shown that...

Charge Resonance and Charge Transfer Interactions

Abstrtct Chrge resonance interaction in naphthalene homomd heterodimer cations is studied by photodissociation spc'troscopy ofthe charge resonance and the local excitation transitions. The resonance interaction in naphthalene dimer cation is slightly weaker than that ofa benzene dimer cation because ofpartial overlapping ofthe respective aromatic rings. A local excitationband ofthe benzene cati...

Single-molecule charge transfer and bonding at an organic/inorganic interface: tetracyanoethylene on noble metals.

We have studied the structural and electronic properties of tetracyanoethylene (TCNE) molecules on different noble-metal surfaces using scanning tunneling spectroscopy and density functional theory. Striking differences are observed in the TCNE behavior on Au, Ag, and Cu substrates in the submonolayer limit. We explain our findings by a combination of charge-transfer and lattice-matching proper...

Modeling the charge transfer between alkali metals and polycyclic aromatic hydrocarbons using electronic structure methods.

The interaction of alkali metals-specifically, lithium-with polycyclic aromatic hydrocarbons (PAHs) was studied using a variety of electronic structure methods. Electron transfer from lithium to a PAH depends on the size and structure of the PAH and the electronic structure method used. In some cases, we observe an artificial transfer when using density functional theory (DFT) due to the self-i...
