我们报告的最小的石墨层间化合物，氯化铁（FeCl3）岛单层内双层石墨烯的合成和传输特性。通过微拉曼光谱和霍尔测量同时探测插层剂的化学掺杂。电导率的量子振荡起源于插入区和未插入区的微观畴。观察到与磁性转变相关的电阻略有上升。二维插层双层石墨烯为设计插层物的二维性质开辟了新的可能性。
We report synthesis and transport properties of the minimal graphite intercalation compound, a ferric chloride (FeCl3) island mono layer inside bilayer graphene. Chemical doping by the intercalant is simultaneously probed by micro Raman spectroscopy and Hall measurements. Quantum oscillations of conductivity originate from microscopic domains of intercalated and uninterealated regions. A slight upturn in resistance related to magnetic transition is observed Two-dimensional intercalation bilayer graphene opens new possibilities to engineer two dimensional Properties of intercalates.
