Femtosecond nonequilibrium dynamics in quasi-1D CDW systems K0.3 MoO3 and RB0.3 MoO3. Tomeljak, A., Kavcic, B., Schäfer, H., Kabanov, V., V., Mihailović, D., Starešinić, D., Biljaković, K., & Demšar, J. Physica B: Condensed Matter, 404(3-4):548-551, 2009.

Here we report on detailed studies of the photoexcited carrier and collective mode dynamics in prototype quasi-1D charge density wave (CDW) systems K0.3 MoO3 and Rb0.3 MoO3 focusing on their low temperature and low excitation range. We show that the order parameter relaxation dynamics are inconsistent with the Rothwarf-Taylor model describing the relaxation of the coupled quasi-particle and high frequency phonon system in a system with a narrow gap in the density of states. Therefore we propose an alternative model that accounts for the photoexcited carrier relaxation phenomena commonly observed in CDW systems. ?? 2008 Elsevier B.V. All rights reserved.
