Abstract

The surfaces of thin films of tin dioxide prepared by radio frequency sputtering have been driven to react with nitrogen by exposure to a proton beam in an atmosphere containing nitrogen gas. Such modification of the composition of the free surfaces of the films modifies their gas response characteristics substantially.

The effects of modifying the surface of tin dioxide by exposure to proton beams in air have been demonstrated for thin films prepared both by tputtering and by dip coating with a sol.
