摘要

石墨烯霍尔元件(GHEs)具有高灵敏度和柔性。我们的GHEs的平均和最大电流相关灵敏度分别为2030 V/AT和2364 V/AT，优于几乎所有报道的霍尔传感器。此外，在柔性衬底上制备的GHEs具有较高的灵敏度、线性度和抗弯曲稳定性。我们的工作表明，石墨烯霍尔传感器在精确检测磁场和柔性传感系统方面具有很大的前景。

Flexible graphene hall sensors with high sensitivity

High sensitivity and flexible Graphene Hall elements (GHEs) were demonstrated. The average and maximum current-related sensitivity of our GHEs are respectively 2030 V/AT and 2364 V/AT, outperforming almost all reported Hall sensors. In addition, the GHEs fabricated on flexible substrate show high sensitivity, linearity and stability against bending. Our work shows that graphene Hall sensors are promising in accurate detection of magnetic field and flexible sensing systems.
