Abstract:
Graphene is known for its many
superlatives – strongest, most impermable,
most conducting, highest thermal
conductivity, etc. But some of its notable
properties disappear in the presence of
defects. I will discuss the effect of single
atom vacancies on graphene's magnetic and
electronic properties as revealed by scanning
tunneling microscopy and spectroscopy.
Topics will include Kondo screening of the
vacancy magneic moment and observation
of the ultra-relativistic analogue of atomic
collapse at a supercritically charged
vacancy.
