Charge transport in polymeric graphitic carbon nitrides is shown to proceed via diffusive hopping of electron and hole polarons with reasonably high mobilities >10(-5) cm(2) V(-1) s(-1). The power-law behavior of the ultrafast luminescence decay exhibits that the predominant transport direction is perpendicular to the graphitic polymer sheets, thus complementing 2D materials like graphene.
聚合物石墨相氮化碳中的电荷输运被证明是通过电子和空穴极化子的扩散跳跃进行的,其迁移率相当高,大于 10(-5) cm(2) V(-1) s(-1)。超快发光衰减的幂律行为表明,主要的输运方向垂直于石墨聚合物片,从而补充了类似石墨烯的二维材料。
