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…

Facile deterministic cutting of 2D materials for twistronics using a tapered fibre scalpel
L. D. Varma Sangani, R. S. Surya Kanthi, Pratap Chandra Adak +5
We present a quick and reliable method to cut 2D materials for creating 2D twisted heterostructures and devices. We demonstrate the effectiveness of using a tapered fibre scalped f…

Tunable bandwidths and gaps in twisted double bilayer graphene system on the verge of correlations
Pratap Chandra Adak, Subhajit Sinha, Unmesh Ghorai +5
We use temperature-dependent resistivity in small-angle twisted double bilayer graphene to measure bandwidths and gaps of the bands. This electron-hole asymmetric system has one se…
