• ]. Therefore, a reliable and accurate investigation of the electronic behavior in devices based on Gr/hBN heterostructures must consider the effect of such defects. In this work, a nanometer-scaled RTD based on lateral AGNR/ABNNR heterojunctions is proposed and the effect of all possible types of
