The two transitions with Chern number changes of 3 and +1 can be explained by the formation of three satellite Dirac points around the central Dirac cone in the moir茅 Brillouin zone due to the presence of trigonal warping. The satellite cones have opposite chirality to the central Dirac cone...

There is a small amount of flattening in the direction of the k c-axis and of trigonal warping around the k c-axis, caused by higher order terms than [ k 2] in the ϵ(k) relation. DOI: 10.1016/0038-1098(73)90242-1 被引量: 14 年份: 1973 ...

The effect of trigonal warping on the transmission of electrons tunneling through potential barriers in graphene is investigated. We present calculations of the transmission coefficient for single and double barriers as a function of energy, incidence angle and barrier heights. The results show remarkable...
