title: Photoinduced hardness change on TiO(2) single crystal surfaces.
abstract: The dynamic hardness of rutile TiO(2) single crystal surfaces was investigated using a nanoindentation technique and the hardness increase was observed only in the near-surface region, possibly due to the volume expansion accompanied by the photoinduced high hydrophilicity.
