Abstract
We discuss electrical transport measurements performed on
thin films of four different metal phthalocyanines doped with Potassium
atoms. The temperature dependence of the conductivity shows that a metallic
state occurs on a wide range of doping concentrations for all the four
molecules. The occurence of the metallic state is confirmed by scanning
tunneling spectroscopy.
Key words. Metal phthalocyanine - band filling - metal -
insulator transition.
