中文摘要：

在2到50K温度范围内测量了单层石墨烯量子霍尔平台与平台之间转变的标度律关系.发现石墨烯的标度律指数κ不是普适的,在低温段的κ大约是0.13,在高温段的κ大约是0.33.这一结果进一步验证了石墨烯中长程散射的主导地位.

英文摘要：

Scaling law of quantum Hall plateau-to-plateau transition in single layer graphene is studied in a temperature range from 2 K to 50 K.We find that the scaling exponent κ is not universal.In a low temperature range,κ is about 0.13,while in a high temperature range,κ is about 0.33.The result indicates the dominance of long range scattering in graphene.
