“…[ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ] In broad terms, 2DLMs represent the emerging atomically thin materials where intramolecular interactions are covalent/ionic forces, whereas the intermolecular interactions are van der Waals (vdW) forces. Inspiringly, the scientific communities have by far identified and produced a broad catalog of 2DLMs beyond graphene, represented by group 15 semiconductors, [ 18 ] nitrides, [ 7 ] transition metal dichalcogenides (TMDCs), [ 19 , 20 , 21 , 22 ] postâtransition metal chalcogenides, [ 23 , 24 ] halides, [ 25 , 26 , 27 , 28 ] multiâelemental compounds, [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ] just to name a few. Benefiting from the prominent electrostatic tunability, danglingâbondâfree top/bottom interface, intrinsic exemption to shortâchannel effects, spatially confined structures, reasonably high carrier mobility, outstanding mechanical strength, and strong interactions with light, these fascinating 2D building blocks have come under the limelight of the nanoâelectronics and nanoâoptoelectronics realms.…”
