Surface dipole of F4TCNQ films: Collective charge transfer and dipole-dipole repulsion in submonolayers
Zoltán G. Soos, Benjamin J. Topham
A charge transfer (CT) model is introduced for strong acceptors like A = F4TCNQ that are ionized on surfaces at low coverage θ. Each A forms a CT dimer with a surface state S. Dipo…
Magnetic susceptibility of alkali-TCNQ salts and extended Hubbard models with bond order and charge density wave phases
Manoranjan Kumar, Benjamin J. Topham, Rui Hui Yu +2
The molar spin susceptibilities of Na-TCNQ, K-TCNQ and Rb-TCNQ(II) are fit quantitatively to 450 K in terms of half-filled bands of three one-dimensional Hubbard models with…
Ionization potentials of crystalline organic thin films: Position dependence due to molecular shape and charge redistribution
Benjamin J. Topham, Manoranjan Kumar, Zoltán G. Soos
In addition to electronic polarization or charge redistribution, the shape of neutral conjugated molecules yields position-dependent ionization potentials and electron affinities i…
