Description

We have investigated an in-plane electrical transport in an individual titania nanosheet, which forms a lepidocrocite structure with a few atomic layer thickness. The conductivity in the titania nanosheet varied five orders for the change of the relative humidity from 45% to 95%. The drastic change in the conductivity is due to a sensitive response with respect to water molecules adsorbed on the surface of the two-dimensional nanosheet. The results may open an avenue for nanodevices built from various oxide nanosheets
