The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon\u2019s current-conducting capabilities via doping, which is a process that introduces either negatively charged electrons or positively charged \u201choles\u201d where electrons used to be. This allows the flow of electricity to be controlled and for silicon involves injecting other atomic elements that can adjust electrons\u2014known as dopants\u2014into its three-dimensional (3D) atomic lattice.<\/p>\n

Silicon\u2019s 3D lattice, however, is too big for next-generation electronics, which include ultra-thin transistors, new devices for optical communication, and flexible bio-sensors that can be worn or implanted in the human body. To slim things down, researchers are experimenting with materials no thicker than a single sheet of atoms, such as graphene<\/a>. But the tried-and-true method for doping 3D silicon doesn\u2019t work with 2D graphene, which consists of a single layer<\/a> of carbon atoms that doesn\u2019t normally conduct a current.<\/p>\n

Rather than injecting dopants, researchers have tried layering on a \u201ccharge-transfer layer\u201d intended to add or pull away electrons from the graphene. However, previous methods used \u201cdirty\u201d materials in their charge-transfer layers; impurities in these would leave the graphene unevenly doped and impede its ability to conduct electricity.<\/p>\n","protected":false},"excerpt":{"rendered":"
