Influence of numerous Moiré superlattices on transport properties of twisted multilayer graphene

The Efficiency Study of Graphene Synthesis on Copper Substrate via Chemical Vapor Deposition Method with Methanol Precursor

“…Very recently, twisted multilayer graphene has been synthesized and found its outstanding transport properties [ 24 ]. Complete demonstration of twisted phase, twist angles, and Moiré superlattices in band structures also has been realized [ 25 ]. Therefore, confirming the quality of graphene and the growth efficiency should be another focus of research because a number of monolayers (less than 10 layers) of graphene still exhibit 2D properties [ 26 ].…”

Flattening conduction and valence bands for interlayer excitons in a moiré MoS2/WSe2 heterobilayer

“…8 As a result, the properties of the excitons can be broadly tuned by flattening the electron and hole bands and changing their moiré potentials, leading to intriguing possibilities for novel technology devices. 7,[9][10][11][12] In homobilayers, moiré patterns occur only in twisted samples but in TMD heterobilayers, because of the incommensurability of the two different TMD lattices, moiré patterns are present even without twisting. Rotational alignment has been found to influence the interlayer coupling in homobilayers, 13 but for TMD heterobilayers, the role and possible tunability of interlayer coupling remain open questions.…”

Manifesting Epoxide and Hydroxyl Groups in XPS Spectra and Valence Band of Graphene Derivatives

“…Engineering two-dimensional materials’ electronic structure has been one of the key issues since their isolation, starting with graphene and followed by metal dichalcogenides layers and elemental two-dimensional materials [ 1 , 2 , 3 ], leveraging the benefits of the materials’ two-dimensional nature. Extensive experimental and theoretical studies are being carried out to approach the management of the materials’ band gap, govern the position of the Fermi level, and arrange the density of states (DOS) in the valence and conduction bands [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Several strategies have been advanced for these purposes—structural nanopatterning [ 5 , 6 ], the formation of Moiré heterostructures [ 7 , 8 ], doping with pnictogen or chalcogen atoms [ 9 ], and chemical functionalization [ 1 , 10 , 11 ].…”

The latter approach has appeared to be the most facile one up to date, particularly for graphene with its inherent ease of being modified by chemical groups with the rise of a large family of its chemical derivatives [ 11 , 12 , 13 ].…”
