Abstract
We probe the dynamics of band gap collapse in the Mott (electronic) insulator ETF2TCNQ and Peierls (structural) insulator K-TCNQ. The collapse of the Mott gap is a purely electronic process occurring within 20 fs. In the Peierls insulator, the gap collapse takes 300 fs, only after a lattice distortion has relaxed.
