Abstract:

We photo-excited a charge-ordered organic salt (EDO-TTF)(2)PF6 with sub- 10-fs optical pulses. The photo-induced metallic phase appeared within 80-fs after pumping, characterized by large changes in reflectivity (Delta R/R similar to 0.8) followed by strong coherent phonon modulation.

Time resolved conductivity dynamics in vanadium dioxide

Abstract:

Optical-pump terahertz-probe spectroscopy is used to investigate the photoinduced insulator-to-metal phase transition in vanadium dioxide. The observed dynamics are consistent with a spatially inhomogeneous insulating state. © 2005 Optical Society of America.
