栅控石墨烯电导率的电压和温度依赖性

Voltage and temperature dependencies of conductivity in gated graphene

F. T. Vasko, V. Ryzhii

摘要:

考虑到电子和空穴散射的栅极石墨烯的电阻率进行了研究,从扫描隧道显微镜的数据和声学声子的无序的特点,从短期和长期的结构缺陷。计算是基于准经典动力学方程与固定的表面电荷的归一化条件。栅电压和温度对电阻峰值的影响,这是集中在本征电导率的点,被发现是在协议的运输测量。

英文摘要:

The resistivity of gated graphene is studied taking into account electron and hole scattering by short- and long-range structural imperfections the characteristics of disorder were taken from the scanning tunneling microscopy data and by acoustic phonons. The calculations are based on the quasiclassical kinetic equation with the normalization condition fixed by surface charge. The gate-voltage and temperature effects on the resistance peak, which is centered at the point of intrinsic conductivity, are found to be in agreement with the transport measurements.
