Topologically Protected Helical States in Minimally Twisted Bilayer Graphene
Shengqiang Huang, Kyounghwan Kim, Dmitry K. Efimkin +6
In minimally twisted bilayer graphene, a moir{é} pattern consisting of AB and BA stacking regions separated by domain walls forms. These domain walls are predicted to support count…
Tunable Moiré Bands and Strong Correlations in Small-Twist-Angle Bilayer Graphene
Kyounghwan Kim, Ashley DaSilva, Shengqiang Huang +7
According to electronic structure theory, bilayer graphene is expected to have anomalous electronic properties when it has long-period moiré patterns produced by small misalignment…
Evolution of the electronic band structure of twisted bilayer graphene upon doping
Shengqiang Huang, Matthew Yankowitz, Kanokporn Chattrakun +2
The electronic band structure of twisted bilayer graphene develops van Hove singularities whose energy depends on the twist angle between the two layers. Using Raman spectroscopy,…
Intrinsic disorder in graphene on transition metal dichalcogenide heterostructures
Matthew Yankowitz, Stefano Larentis, Kyounghwan Kim +8
The electronic properties of two-dimensional materials such as graphene are extremely sensitive to their environment, especially the underlying substrate. Planar van der Waals bond…
Gate dependent Raman spectroscopy of graphene on hexagonal boron nitride
Kanokporn Chattrakun, Shengqiang Huang, K. Watanabe +3
Raman spectroscopy, a fast and nondestructive imaging method, can be used to monitor the doping level in graphene devices. We fabricated chemical vapor deposition (CVD) grown graph…
