Structure and electronic properties of bilayer type molecularconductors based on ETTM-STF

摘要

We synthesized asymmetrical donor molecules for searching uniquecrystal structures and electronic properties.For example,an ambientpressuremolecular superconductor (TMET-STF)2BF4 (Tc = 4.1 K) hastwo crystallographically independent cation radical layers,which iscalled bilayer structure.The band structure calculation indicates thatthe one conduction layer has a quasi-one-dimensional Fermi surfaceand the other layer a cylindrical two-dimensional Fermi surface.
