▎ 摘　　要

We performed electric and thermoelectric transport measurements of bilayer graphene in a magnetic field up to 15 T. The transverse thermoelectric conductivity alpha(xy), determined from four transport coefficients, attains a peak value of alpha(xy,peak) whenever chemical potential lies in the center of a Landau level. The temperature dependence of alpha(xy,peak) is dictated by the disorder width W(L). For k(B)T/W(L)= 0.5, alpha(xy,peak) saturates to a value close to the predicted universal value of 4x(ln 2)k(B)e/h according to the theory of Girvin and Jonson. We remark that an anomaly is found in alpha(xy) near the charge neutral point, similar to that in single- layer graphene.
