Query: Large Fermi energy modulation in graphene transistors with high-pressure
  O2-annealed Y2O3 topgate insulators   We demonstrate a considerable suppression of the low-field leakage through a
Y2O3 topgate insulator on graphene by applying high-pressure O2 at 100 atm
during post-deposition annealing (HP-PDA). Consequently, the quantum
capacitance measurement for the monolayer graphene reveals the largest Fermi
energy modulation (EF = ~0.52 eV, i.e., the carrier density of ~2*10^13 cm^-2)
in the solid-state topgate insulators reported so far. HP-PDA is the robust
method to improve the electrical quality of high-k insulators on graphene.
