Probing work and heat dissipation in the quantum Hall edges
of graphene

22nd October 2019by admin0

Combining our nano-SQUID on tip with scanning gate
measurements in the quantum Hall phase of graphene we were able to
measure and identify work and heat dissipation processes
separately. The measurements show that the dissipation is governed
by crosstalk between counterpropagating pairs of downstream and
upstream channels that appear at graphene boundaries because of
edge reconstruction.

    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.
