    © 2016 Macmillan Publishers Limited. All rights reserved.The superconducting transition temperature in a FeSe monolayer on SrTiO3 is enhanced up to 100 K. High TC is also found in bulk iron chalcogenides with similar electronic structure to that of monolayer FeSe, which suggests that higher TC may be achieved through electron doping, pushing the Fermi surface topology towards leaving only electron pockets. Such an observation, however, has been limited to chalcogenides, and is in contrast to the…Read more
