Abstract:
We propose an explanation for the appearance of superconductivity
at the interfaces of graphite with Bernal stacking order. A
network of line defects with flat bands appears at the interfaces
between two slightly twisted graphite structures. Due to the flat
band the probability to find high temperature superconductivity at
these quasi one-dimensional corridors is strongly enhanced. When
the network of superconducting lines is dense it becomes
effectively two-dimensional. The model provides an explanation
for several reports on the observation of superconductivity up to
room temperature in different oriented graphite samples, graphite
powders as well as graphite-composite samples published in the
past.
