The first image of the week of 2016 comes from our recently published special issue on 2D semiconductors. There are many techniques used to manipulate graphene’s crystal structure in order to take advantage of its many extraordinary properties. S M Hollen et al examine the development of native defects in graphene grown by the UHV method. Using scanning tunnelling microscopy they observe two types of defects and how these affect the graphene lattice.

The work provides further insight into how growth techniques may be used to program defect density in graphene crystals for controllable doping and functionalization for use in graphene devices. You can read the full article here.
