We have shown that the room-temperature adsorption of the biphenyl molecule on the Si(100) surface gives rise in majority to a bistable molecular configuration. The switching of the bistable molecule is activated at room temperature by thermal activation. By using a combination of room-temperature and low-temperature (30 K) scanning tunneling microscope (STM) topography, room-temperature STM manipulation, and near edge x-ray absorption fine structure spectroscopy, the nature of the bistable molecule, its adsorption geometry, and its interaction with the surface could be identified.
