Unraveling the magnetism of a graphene triangular
flake

11th May 2020by admin0

Graphene is a diamagnetic material, this is, unable of
becoming magnetic. However, a triangular piece of graphene is
predicted to be magnetic. This apparent contradiction is a
consequence of “magic” shapes in the structure of graphene flakes,
which force electrons to “spin” easier in one direction.
Triangulene is a triangular graphene flake, which possesses a net
magnetic moment: it is a graphene nanometer-size magnet. This
magnetic state opens fascinating perspectives on the use of these
pure-carbon magnets in technology.

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
