Designing Flat Bands and Pseudo-Landau Levels in GaAs with Patterned Gates
Pierre A. Pantaleon, Zhen Zhan, Siddhartha E. Morales +1
We investigate the electronic properties of two-dimensional electron gases (2DEGs) subjected to a periodic patterned gate. By incorporating the superlattice (SL) potential induced…
Designing Band Structures by Patterned Dielectric Superlattices
Zhen Zhan, Yonggang Li, Pierre A. Pantaleon
We investigate the electronic structure of graphene monolayers subjected to patterned dielectric superlattices. Through a quantum capacitance model approach, we simulate realistic…
Strain and twist angle driven electronic structure evolution in twisted bilayer graphene
Jiawei Yu, Guihao Jia, Qian Li +14
In twisted bilayer graphene (TBG) devices, local strains frequently coexist and intertwine with the twist-angle-dependent moiré superlattice, significantly influencing the electron…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Infrared Spectroscopy for Diagnosing Superlattice Minibands in Magic-angle Twisted Bilayer Graphene
Geng Li, Roshan Krishna Kumar, Petr Stepanov +11
Twisted bilayer graphene (TBG) represents a highly tunable, strongly correlated electron system owed to its unique flat electronic bands. However, understanding the single-particle…
Robust flat bands in twisted trilayer graphene quasicrystals
Chen-Yue Hao, Zhen Zhan, Pierre A. Pantaleón +6
Moiré structures formed by twisting three layers of graphene with two independent twist angles present an ideal platform for studying correlated quantum phenomena, as an infinite s…
