Highly Selective Synthesis of C₆₀ Disks on Graphite Substrate by a Vapor-Solid Process

New jobs for disk jockeys: Single‐crystalline C60 disks were selectively synthesized on an HOPG substrate by a vapor–solid process with C60 powder as the precursor. The photoluminescence intensity of the disks is much greater than that of thin films and powders. In photoconductivity measurements wit...

Zusammenfassung:New jobs for disk jockeys: Single‐crystalline C60 disks were selectively synthesized on an HOPG substrate by a vapor–solid process with C60 powder as the precursor. The photoluminescence intensity of the disks is much greater than that of thin films and powders. In photoconductivity measurements with a single disk the current was increased by about tenfold. These properties point to intriguing applications.
