We report on the observation of photoconductivity in elemental gallium confined at an interface with glass. The effect is associated with a fully reversible light-induced structural transformation in the metal, which affects a surface layer only a few nanometers thick. The effect has the potential for applications in optically fast, broadband photodetectors.
