Abstract
Triazine‐based graphitic carbon nitride (TGCN) is the most recent addition to the family of graphene‐type, two‐dimensional and metal‐free materials. Although hailed as a promising low‐bandgap semiconductor for electronic applications, so far, only its structure and optical properties have been known. Here, we combine direction‐dependent electrical measurements and time‐resolved optical spectroscopy to determine macroscopic conductivity and microscopic charge carrier mobilities in this layered material “beyond graphene”. Electrical conductivity along the basal plane of TGCN is 65‐times lower than through the stacked layers; as opposed to graphite. Furthermore, we...
