Query: p-wave triggered superconductivity in single layer graphene on an
  electron-doped oxide superconductor   Electron pairing in the vast majority of superconductors follows the
Bardeen-Cooper-Schrieffer theory of superconductivity, which describes the
condensation of electrons into pairs with antiparallel spins in a singlet state
with an s-wave symmetry. Unconventional superconductivity is predicted in
single layer graphene where the electrons pair with a p-wave or chiral d-wave
symmetry, depending on the position of the Fermi energy with respect to the
Dirac point. By placing single layer graphene on an electron-doped (non-chiral)
d-wave superconductor and performing local scanning tunnelling microscopy and
spectroscopy, here we show evidence for a p-wave triggered superconducting
density of states in single layer graphene. The realization of unconventional
superconductivity in single layer graphene offers an exciting new route for the
development of p-wave superconductivity using two-dimensional materials with
transition temperatures above 4.2 K.
