Evidence for the formation of a Mott state in potassium-intercalated pentacene
M. F. Craciun, G. Giovannetti, S. Rogge +3
We investigate electronic transport through pentacene thin-films intercalated with potassium. From temperature-dependent conductivity measurements we find that potassium-intercalat…
Electronic structure and correlations in pristine and potassium doped Cu-Phthalocyanine molecular crystals
Gianluca Giovannetti, Geert Brocks, Jeroen van den Brink
We investigate the changes in the electronic structure of copper phthalocyanine (CuPc) crystals that is caused by intercalation with potassium. This is done by means of {\it ab ini…
Electronic Correlations in Oligo-acene and -thiophene Organic Molecular Crystals
Geert Brocks, Jeroen van den Brink, Alberto F. Morpurgo
From first principles calculations we determine the Coulomb interaction between two holes on oligo-acene and -thiophene molecules in a crystal, as a function of the oligomer length…
