CONDUCTIVE FULLERENE SOLID AND ITS PRODUCTION

摘要

PURPOSE: To make either p or n-type fullerene semiconductor and to obtain a semiconductor having optional conductivity without a change on ageing and with stable physical properties by forming a fullerene solid from hollow fullerene and metallofullerene. CONSTITUTION: A conductive fullerene is formed with at least one kind of molecule with the ratio to the total number of molecules controlled to 0.0001-0.9999 and selected from hollow fullerenes and at least one kind of molecule with the ratio to the total number of molecules controlled to 0.0001-0.9999 and selected from metallofullerenes. The fullerene solid is synthesized by dissolving the hollow fullerene and metallofullerene in their common solvent such as toluene and then vaporizing the solvent or by sealing the crystal powders of the hollow fullerene and metallofullerene in a quartz tube and growing the crystal at a temp. gradient by sublimation. Further, a thin film is formed on a substrate by vapor deposition, MBE, ion cluster beam method, etc.
