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…

Non-trivial quantum oscillation geometric phase shift in a trivial band
Biswajit Datta, Pratap Chandra Adak, Li-kun Shi +4
The accumulation of non-trivial geometric phases in a material's response is often a tell-tale sign of a rich underlying internal structure. Studying quantum oscillations provides…
