Fermi Surface Topology and Electronic Structures of Two-Dimensional Organic Conductors Based on BEDT-TTF and MDT-TTF

Abstract The electronic structures of two series of quasi-2D organic metals, α-(ET)2MHg(SCN)4, (M=K, NH4) and θ-(MDT-TTF)2 Au (CN)2, are discussed based on the resistivity measurements using high magnetic field up to 35T or an application of pressure.
