Abstract

We have discovered two-dimensional zero-gap material with a layered structure in the organic conductor $��$-(BEDT-TTF)$_2$I$_3$ under high hydrostatic pressure. In contrast to graphene, the electron-hole symmetry is not good except at the vicinity of the Dirac points. Thus, temperature dependence of the chemical potential, $��$, plays an important role in the transport in this system. The experimental formula of $��$ is revealed. We succeeded in detecting the inter-band effects of a magnetic field on the Hall conductivity when $��$ passes the Dirac point., 5 page, 4 figures
