Scientists and engineers are excitedly mixing and matching these emerging materials to produce tailored materials optimized for a wide range of functions.

New materials can change the world. There is a reason we talk about the Bronze Age and the Iron Age. Concrete, stainless steel, and silicon made the modern era possible. Now a new class of materials, each consisting of a single layer of atoms, are emerging, with far-reaching potential. Known as two-dimensional materials, this class has grown within the past few years to include lattice-like layers of carbon (graphene), boron (borophene) and hexagonal boron nitride (aka white graphene), germanium (germanene), silicon (silicene), phosphorous (phosphorene) and tin (stanene). More 2-D materials have been shown theoretically possible but not yet synthesized, such as graphyne from carbon. Each has exciting properties, and the various 2-D substances can be combined like Lego bricks to build still more new materials.
