Abstract

We have studied the ammonia pressure dependence and composition dependence of the a-axis electrical resistivity of the potassium-ammonia ternary graphite intercalation compounds K(NH3)XC2 4, O < × < 4.33. Our results show evidence of the 2D analog of the well-studied bulk 3D metal-insulator transition [1] in bulk K-NH3 solutions.
