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”.

Disorder in twisted bilayer graphene

Physical Review Research, 2020
We develop a theory for a type of disorder in condensed matter systems arising from local twist-angle fluctuations in two strongly coupled van der Waals monolayers twisted with respect to each other to create a flat-band moiré superlattice.

Twist-Dependent Electronic Coupling in an Organic Intervalence Radical Cation

, 2016
The nearly 90° twist between the reduced dialkylaniline π system and the oxygen atom p lone pair orbital limits electronic interaction between the reduced and oxidized aniline units and makes varying this twist angle a principal factor that facilitates ...

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.

Tunable Electronic Structure in Twisted Bilayer WTe2

Frontiers in Physics, 2022
The moiré pattern restricts the electronic states of transition metal bilayers, thus extending the concept of the magic angle found in twisted bilayer graphene to semiconductors.
