I will discuss new and surprising phenomena that emerge when the perfect honeycomb lattice of graphene is disrupted. In particular I will focus on the effects of single atom vacancies on graphene’s electronic and magnetic properties as revealed by scanning tunneling microscopy and spectroscopy.
These include the ability to charge the vacancy site into the supercritical regime where an artificial atom forms, and electrostatically controlled screening of the vacancy magnetic moment.
