Query: Evidence of Water-related Discrete Trap State Formation in Pentacene
  Single Crystal Field-Effect Transistors   We report on the generation of a discrete trap state during negative gate
bias stress in pentacene single crystal "flip-crystal" field-effect transistors
with a SiO2 gate dielectric. Trap densities of up to 2*10^12 cm^-2 were created
in the experiments. Trap formation and trap relaxation are distinctly different
above and below ~280 K. In devices in which a self-assembled monolayer on top
of the SiO2 provides a hydrophobic insulator surface we do not observe trap
formation. These results indicate the microscopic cause of the trap state to be
water adsorbed on the SiO2 surface.
