Graphene, a single-atom-thick sheet of carbon
Position 1: Researchers are therefore exploring chemical functionalization and layered heterostructures as strategies to engineer a controllable band gap into the material.
Position 2: Its tensile strength is approximately two hundred times greater than that of steel, despite its negligible mass per unit area.
Position 3: However, the absence of a natural band gap has so far prevented graphene from fully replacing silicon in semiconductor applications.
Position 4: Graphene, a single-atom-thick sheet of carbon arranged in a hexagonal lattice, possesses extraordinary mechanical and electrical properties.
Position 5: Furthermore, electrons travel through graphene with almost no resistance at room temperature, making it a promising candidate for next-generation transistors.
