论文摘要
我们报告了双门控六角硼(HBN)/双层 - 格拉烯(BLG)超晶格中的运输特性。在这里,blg是非狂热的,即平原。本文重点介绍了普通BLG的电荷中立点(CNP)。在垂直的磁场下,通过对抗性 - 温度特性和磁性磁性的研究来改变位移场,从而检测到CNP处两个绝缘阶段之间的过渡。这项工作为探索CNP以外的HBN/BLG超晶格的全局相图开放了途径。
We report on transport properties in dual-gated hexagonal boron nitride (hBN)/bilayer-graphene (BLG) superlattices. Here, BLG is nontwisted, i.e., plain. This paper focuses on the charge neutrality point (CNP) for a plain BLG. Under a perpendicular magnetic field, transitions between two insulating phases at the CNP are detected by varying a displacement field with the study on the resistance-temperature characteristics and the magnetoresistance. This work opens avenues for exploring the global phase diagram of the hBN/BLG superlattices beyond the CNP.
