Using FIM, we have studied the atomic structure of thermally equilibrated surfaces of silicon and metals. The (1x2) reconstruction of Pt and Ir (110), the (1x5) reconstruction of Ir (001) and the reconstruction of Pt (001) can be directly observed with a pulsed-laser-heating technique. Images of atomically resolved and well ordered silicon surfaces are obtained for the first time with FIM. Most surfaces are reconstructed. Two distinctly different structures are found for the Si (023) and some other surfaces.
