Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Three of the four outer-shell electrons of each atom in a graphene sheet occupy three sp hybrid orbitals – a combination of orbitals s, px and py — that are shared with the three nearest atoms, … WebAug 1, 2015 · Recent development in 2D materials beyond graphene. Discovery of graphene and its astonishing properties have given birth to a new class of materials known as “2D materials”. Motivated by the success of graphene, alternative layered and non-layered and their assembly. Electronic, magnetic, optical and mechanical properties of …
