Electronic Properties of Twisted Bilayer Graphene in the Presence of a Magnetic Field [PDF]
EPJ Web of Conferences, 2020 In AA-stacked twisted bilayer graphene, the lower energy bands become completely flat when the twist angle passes through certain specific values: the so-called “magic angles”.

Theoretical Investigation of Twist-Angle-Dependent Photoelectric Properties in Twisted Bilayer WSe<sub>2</sub>. [PDF]
MoleculesThe twist angle serves as a geometric tuning parameter in two-dimensional layered materials, enabling modulation of interlayer coupling and band structures without altering the chemical composition. In this work, six commensurate twisted bilayer WSe2 configurations with rotation angles of 0°, 9.4°, 13.14°, 21.9°, 27.8°, and 60° were systematically ...

Experimental evidence for interlayer decoupling distance of twisted bilayer graphene
AIP Advances, 2018 Twisted bilayer graphene (tBLG) is two stacked single graphene sheets rotated at a specific angle. The twist angle plays an important role in the physical properties of the tBLG.

The ten helical twist angles of B-DNA
Nucleic Acids Research, 1982 On the assumption that the twist angles between adjacent base-pairs in the DNA molecule are additive a linear system of 40 equations was derived from experimental measurements of the total twist angles for different pieces of DNA of known sequences.

Twist-Stabilized, Coiled Carbon Nanotube Yarns with Enhanced Capacitance
, 2022 Coil-structured carbon nanotube (CNT) yarns have recently attracted considerable attention. However, structural instability due to heavy twist insertion, and inherent hydrophobicity restrict its wider application. We report a twist-stable and hydrophilic
