Coexistence of Dirac and massive carriers in α-(BEDT-TTF)2I3 under hydrostatic pressure
Résumé
We present magnetotransport measurements of α-(BEDT-TTF)2I3 crystals under hydrostatic pressure larger than 1.5 GPa where Dirac carriers are present. We show not only the existence of high-mobility Dirac carriers but we also prove exptl. the presence of low-mobility massive carriers, in agreement with band-structure calcns.
