Photo-induced carrier dynamics were measured in the organic Dirac electron candidate α -(BETS) 2 I 3 to investigate why resistivity increases below T MI = 50 K. We found a change in carrier dynamics due to an insulating gap formation below T ′ = 50 K. On the other hand, the relaxation time and polarization anisotropy of the observed dynamics differ from those in the charge-ordering (CO) state of the isostructural salt α -(ET) 2 I 3 . Based on the difference, it can be concluded that the insulating phase has a different origin than the CO state. [ABSTRACT FROM AUTHOR] |
