Abstract

Transport measurements for different electron-doped metal–phthalocyanine (MPc) materials are reported by Morpurgo and co-workers on p. 320. It is experimentally demonstrated that for these doped MPc materials, increasing the doping level results first in a metallic state and, subsequently, in the re-entrance of an insulating state. The artist's impression on the inside cover shows an MPc film situated between two electrodes and exposed to a flux of alkali atoms in vacuum. The alkali atoms intercalate and donate electrons to the molecular material.
