A phase diagram for light-induced superconductivity in κ-(ET)2-X

> Full text via publisher
Resonant optical excitation of certain molecular vibrations in κ-(BEDT-TTF)2Cu[N(CN)2]Br has been shown to induce transient superconducting-like optical properties at temperatures far above equilibrium Tc. Here, we report experiments across the bandwidth-tuned phase diagram of this class of materials, and study the Mott insulator κ-(BEDT-TTF)2Cu[N(CN)2]Cl and the metallic compound κ-(BEDT-TTF)2Cu(NCS)2. We find non-equilibrium photoinduced superconductivity only in κ-(BEDT-TTF)2Cu[N(CN)2]Br, indicating that the proximity to the Mott insulating phase and possibly the presence of preexisting superconducting fluctuations are pre-requisites for this effect.
