Bandwidth tuning triggers interplay of charge order and superconductivity in two-dimensional organic materials

S. Kaiser, M. Dressel, Y. Sun +4

We observe charge-order fluctuations in the quasi-two-dimensional organic superconductor ${\beta }^{\prime \prime }$-(BEDT-TTF)2 SF5 CH2 CF2 SO3 both by means of vibrational spectroscopy, l…
