Abstract

The relationship between the crystal structure and Fermi surface of the α-(BEDT-TTF)2MHg(XCN)4 (M = T1, K, NH4; X = S, Se) molecular metals is discussed. A simple model to explain the origin of the different dimensionality of the carriers, i.e. one-dimensional (1D) holes but two-dimensional (2D) electrons, is presented.
