Abstract

In this article, we have reviewed our recent experimental study of quantum criticality of Mott metal-insulator transition in organic materials. Resistivity measurements of three organic systems with different ground states were performed under continuously controlled pressure by using helium as a pressure medium. The resistivity obeyed the material-independent quantum-critical scaling relation bifurcating into a Fermi liquid or Mott insulator, irrespective of the ground states.
