Part A Graphene is...
Part A Graphene is a material consisting of a single sheet of atoms taken from a piece of graphite. It has a honeycomb structure with carbon atoms sitting at the corners of a hexagon, about 0.142 nm apart. Consider a graphene sheet that was subjected to a plasma process, where electrons were removed from the carbon atoms. The figure below shows a small hexagonal ring where each carbon atom lost one electron. What is the electric potential at the center of this hexagonal region? 0.284 nm 0.142 nm OOOO 43 V O-43V 61 V 10 V
