Alternating current properties of bulk- and nanosheet-graphitic carbon nitride compacts at elevated temperatures.

ABSTRACT: The investigations of temperature-dependent electrical properties in graphitic carbon nitride (g-C₃N₄) have been largely performed at/below room temperature on devices commonly fabricated by vacuum techniques, leaving the gap to further explore its behaviors at high-temperature. We reported herein the temperature dependence (400 → 35 °C) of alternating current (AC) electrical properties in bulk- and nanosheet-g-C₃N₄ compacts simply prepared by pelletizing the powder. The bulk sample was synthesized via the direct heating of urea, and the subsequent HNO₃-assisted thermal exfoliation yielded the nanosheet counterpart. Their thermal stability was confirmed by variable-temperature X-ray diffraction, demonstrating reversible interlay
