Hexagonal BN is one of the most interesting 2D semiconductors, as it exhibits DUV lights. However, universal consensus has not yet been established for its fundamental optoelectronic properties. In this presentation, emission dynamics of powder BN microcrystals will be discussed using our spatio-time-resolved cathodoluminescence equipment.
