摘要：

We report the first experimental observation of C3N4 single crystals, which are about tens nanometers to several micrometers in length and hundreds nanometers in across. by scanning electron microscopy. The pure crystalline C-N solids with alpha- and beta-phases were grown on nickel substrates by bias-assisted hot filament chemical vapor deposition (bias-HFCVD). Our experimental results are in very good agreement with recent first-principles calculations.
