Superconductivity is a physical phenomenon where the
electrical resistance of a material drops to zero under a certain
critical temperature. Bardeen-Cooper-Schrieffer (BCS) theory is a
well-established explanation that describes superconductivity in
most materials. It states that Cooper pairs of electrons are formed
in the lattice under sufficiently low temperature and that BCS
superconductivity arises from their condensation. While graphene
itself is an excellent conductor of electricity, it does not
exhibit BCS superconductivity due to the suppression of
electron-phonon interactions. This is also the reason that most
‘good’ conductors such as gold and copper are ‘bad’
superconductors.

    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.
