Figure 6: Changes of transition temperature by reducing transfer integral.
From: Optical freezing of charge motion in an organic conductor
(a) The hole densities (ρH) at the A and A' molecules in Fig. 1a as a function of the normalized temperature T/TCO, calculated using the Hartree–Fock approximation for an extended Hubbard model36 for t0, 0.95t0, 0.9t0 and 0.85t0 (circles, squares, triangles and inverted triangles, respectively). (b) Change in TCO (=ΔTCO/TCO) as a function of decreasing transfer integral t (−Δt/t) shown by the black closed circles. The dashed line serves as a guide to the eye. The dashed red arrows indicate that a 10% reduction in t causes a 12% increase in TCO.
