Gas-sensitive electrical conduction is reported in a gold thin film with a locally discontinuous structure. Two novel features were found. Firstly, irregular current pulsation was induced under a stream of helium gas. Secondly, the pulsation was suppressed by adsorption of gas molecules such as oxygen, carbon monoxide, and hydrogen. These phenomena are tentatively interpreted in terms of atomic rearrangement of the gold surface.
