Local Kondo temperatures in atomic chains
Ricardo Agundez, Joe Salfi, Sven Rogge +1
We study the effect of disorder in strongly interacting small atomic chains. Using the Kotliar- Ruckenstein slave-boson approach we diagonalize the Hamiltonian via scattering matri…
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…
Evolution of the conductivity of potassium-doped pentacene films
M. F. Craciun, S. Rogge, A. F. Morpurgo
We have investigated the evolution of the temperature-dependent conductivity of electron-doped pentacene (PEN) thin films, in which the electron density is controlled by means of p…
