摘要: Abstract Inspired by the synthesis of nanometer-scale graphene quantum dots via a doping process in boron nitride (BN) sheets (Adv. Mater. 2019, 1805778), we investigated magnetic and thermal spin transport properties armchair BN nanoribbons containing nanoscale domains. It was found that both M-QB M-QN structures were bipolar semiconductors (BMSs). Two caloritronics devices designed on basis 15-6B 15-6N nanoribbons. Spin-dependent Seebeck effects, spin-dependent diode effects thermoelectric observed these devices. This work provides theoretical guidance for design new
