“…Therefore, because of its promise for large-area electronic applications, a detailed understanding of the electrical transport properties of polycrystalline graphene is crucial. To this end, a great deal of experimental [13,[18][19][20][21][22][23][24][25][26][27] and theoretical [7,[28][29][30][31][32][33][34][35][36][37][38] effort has has been devoted to studying charge transport across individual graphene GBs, and several reviews have already discussed this topic in great detail [5,26,39]. Therefore, here we briefly summarize the main features of electrical transport across individual graphene GBs before shifting our focus to a more global perspective of charge transport in polycrystalline graphene.…”

“…To realize valleytronic devices based on 2D atomic crystals, it is necessary to produce a valley polarization in 2D atomic crystals, which selectively fills or depletes valleys. 84,85,87 Figure 3 shows valley configurations of neutral (X 0 ), negatively charged (X À ) and positively charged (X + ) excitons in monolayer MoX 2 and WX 2 (X = S or Se). 88 Valley polarization in 2D atomic crystals has been investigated by magnetic field and optical pumping.…”

“…[13][14][15][16][17][18][19][20]22 The key mechnism exploited is the valley-dependent intravalley scattering at oblique incidences upon the line scatters. [13][14][15][16][17][18][19][20] In such case, the lateral junction induces valley currents by permeating carriers of one valley more than the other, without producing net outward valleypolarized flows.…”
