石墨烯中带电杂质的谷间散射

Intervalley scattering by charged impurities in graphene

L. S. Braginsky, M. V. Entin

摘要:

谷间带电杂质散射过程进行检查。结果表明,杂质与库仑相互作用使散射几率增加了索末菲因子$F_Z\propto ε^{2\sqrt{1-4g^2}-2}$,其中$ε$为电子能量,$g$为库仑相互作用的无量纲常数.

英文摘要:

Intervalley charged-impurity scattering processes are examined. It is found that the scattering probability is enhanced due to the Coulomb interaction with the impurity by the Sommerfield factor $F_Z\propto ε^{2\sqrt{1-4g^2}-2}$, where $ε$ is the electron energy and $g$ is the dimensionless constant of the Coulomb interaction.
