Electron-hole asymmetry and band gaps of commensurate double moire patterns in twisted bilayer graphene on hexagonal boron nitride
Jiseon Shin, Youngju Park, Bheema Lingam Chittari +1
Spontaneous orbital magnetism observed in twisted bilayer graphene (tBG) on nearly aligned hexagonal boron nitride (BN) substrate builds on top of the electronic structure resultin…
Ultra-high-resolution imaging of moiré lattices and superstructures using scanning microwave impedance microscopy under ambient conditions
Kyunghoon Lee, M. Iqbal Bakti Utama, Salman Kahn +13
Two-dimensional heterostructures with layers of slightly different lattice vectors exhibit a new periodic structure known as moire lattices. Moire lattice formation provides a powe…
Gate tunable topological flat bands in twisted monolayer-bilayer graphene
Youngju Park, Bheema Lingam Chittari, Jeil Jung
We investigate the band structure of twisted monolayer-bilayer graphene (tMBG), or twisted graphene on bilayer graphene (tGBG), as a function of twist angles and perpendicular elec…
Bulk valley transport and Berry curvature spreading at the edge of flat bands
Subhajit Sinha, Pratap Chandra Adak, R. S. Surya Kanthi +6
2D materials based superlattices have emerged as a promising platform to modulate band structure and its symmetries. In particular, moiré periodicity in twisted graphene systems pr…
Valley-Current Splitter in Minimally Twisted Bilayer Graphene
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic transport properties at the intersection of three topological zero-lines as the elementary current partition node that arises in minimally twisted bilayer g…
