TLDR
In the crystal of β-(BEDT-TTF)2PF6, BEDT TTF (bis(ethylenedithiolo)tetrathiafulvalene) molecules are arranged side-by-side.Abstract:
In the crystal of β-(BEDT-TTF)2PF6, BEDT-TTF (bis(ethylenedithiolo)tetrathiafulvalene) molecules are arranged side-by-side. The anisotropy of the electrical resistivity shows that β-(BEDT-TTF)2PF6 is the first organic conductor where the conductivity is the largest along the direction parallel to the molecular plane. The metal-insulator transition is observed at 297 K. The thermoelectric power corresponds to that due to the hole conduction in highly correlated system.read more

Band structure parameters for solid TTFTCNQ
TL;DR: In this paper, molecular orbitals for the highest occupied states of TTF + and TCNQ −, calculated by the Extended Huckel Method of Hoffman, are used to compute band parameters within the tight-binding approximation for the conduction band of solid TTFTCNQ.
