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,…
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…
Optical thickness determination of hexagonal Boron Nitride flakes
Dheeraj Golla, Kanokporn Chattrakun, Kenji Watanabe +3
Optical reflectivity contrast provides a simple, fast and noninvasive method for characterization of few monolayer samples of two-dimensional materials. Here we apply this techniqu…
