Synthesis and characterization of single-crystalline graphitic C3N4 nanocones

Single-crystalline g-C3N4 nanocones (g-CNNCs) were successfully synthesized on nickel-covered silicon (100) substrates supported on a graphite frame using a novel plasma sputtering reaction deposition method. The g-CNNCs have the characteristic photoluminescence peak of g-C3N4 and the longitudinal resistivity belonging to a semiconductor, which results in them having many potential applications.
