“…Other methods have been proposed for opening up an energy gap in graphene [ 4 , 37 ], and, in particular, the introduction (by means of techniques such as e-beam lithography, diblock copolymer, nanosphere and nanoimprint lithography [ 38 , 39 , 40 , 41 , 42 , 43 , 44 ]) of a lattice of perforations (antidots) [ 45 , 46 , 47 ].…”
We perform a numerical simulation of the effects of an orthogonal magnetic field on charge transport and shot noise in an armchair graphene ribbon with a lattice of antidots. This study relies on our envelope-function based code, in which the presence of antidots is simulated through a nonzero mass term and the magnetic field is introduced with a proper choice of gauge for the vector potential. We observe that by increasing the magnetic field, the energy gap present with no magnetic field progressively disappears, together with features related to commensurability and quantum effects. In particular, we focus on the behavior for high values of the magnetic field: we notice that when it is sufficiently large, the effect of the antidots vanishes and shot noise disappears, as a consequence of the formation of edge states crawling along the boundaries of the structure without experiencing any interaction with the antidots.
“…Tan et al [1] provided a detailed review of recent advances in ultrathin 2D materials along with their synthetic methods, characterisation techniques, and applications. The 2D materials that have been explored in various applications include group III monolayer of borophene [2], group IV monolayer of graphene [3–6] and graphene‐like 2D materials [7], silicene [8] and stanene [9, 10], group V monolayer of phosphorene [11], transition metal dichalcogenides [12], and metal chalcogenides such as GaTe [13] and InSe [14]. Very recently, a group VI material called tellurene (single layer of tellurium) has been added to the list.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
