2D layered materials and heterostructures: Past, present, and a bright future

Two-dimensional (2D) materials are ultrathin layered materials that serve as building blocks for engineering properties at the atomic scale. By harnessing the design space of these versatile pieces of matter, advanced technologies integrated into everyday life will be possible in the not-so-distant future. Here, we introduce three perspective articles addressing the past, present, and future of 2D materials and heterostructures.
