Revealing the conduction band and pseudovector potential in 2D moiré semiconductors
Abigail J. Graham, Heonjoon Park, Paul V. Nguyen +12
Stacking monolayer semiconductors results in moiré patterns that host many correlated and topological electronic phenomena, but measurements of the basic electronic structure under…
Robustness of momentum-indirect interlayer excitons in MoS2/WSe2 heterostructure against charge carrier doping
Ekaterina Khestanova, Tatyana Ivanova, Roland Gillen +13
Monolayer transition-metal dichalcogenide (TMD) semiconductors exhibit strong excitonic effects and hold promise for optical and optoelectronic applications. Yet, electron doping o…
Moiré superlattice effects and band structure evolution in near-30-degree twisted bilayer graphene
Matthew J. Hamer, Alessio Giampietri, Viktor Kandyba +6
In stacks of two-dimensional crystals, mismatch of their lattice constants and misalignment of crystallographic axes lead to formation of moiré patterns. We show that moiré superla…
Atomic and electronic structure of two-dimensional Mo(1-x)WxS2 alloys
Xue Xia, Siow Mean Loh, Jacob Viner +8
Alloying enables engineering of the electronic structure of semiconductors for optoelectronic applications. Due to their similar lattice parameters, the two-dimensional semiconduct…
Ghost anti-crossings caused by interlayer umklapp hybridization of bands in 2D heterostructures
Abigail J. Graham, Johanna Zultak, Matthew J. Hamer +13
In two-dimensional heterostructures, crystalline atomic layers with differing lattice parameters can stack directly one on another. The resultant close proximity of atomic lattices…
Visualizing electrostatic gating effects in two-dimensional heterostructures
Paul V. Nguyen, Natalie C. Teutsch, Nathan P. Wilson +9
The ability to directly observe electronic band structure in modern nanoscale field-effect devices could transform understanding of their physics and function. One could, for examp…
