Similar to placing a carpet on a staircase, terraced graphene is formed by stacking a layer of graphene on an atomically terraced substrate. This leads to topographic corrugations and charge puddles in the terraced graphene. In the presence of a magnetic field, its resistance can change as high as 5000% at room temperature, paving a route for extremely sensitive and high‐resolution magnetic sensors, as revealed by Ariando Ariando and co‐workers in article number 2002201.

石墨烯：梯田单层石墨烯中的室温巨磁电阻（Adv。Mater。37/2020）

与在楼梯上放置地毯类似，通过在原子阶梯状衬底上堆叠一层石墨烯来形成阶梯状石墨烯。这导致了梯形石墨烯中的形貌波纹和电荷坑。如阿里安多·阿里安多（Ariando Ariando）及其同事在文章编号2002201中所揭示的，在存在磁场的情况下，其电阻在室温下的变化可能高达5000％，这为极其敏感和高分辨率的磁传感器铺平了道路。
