A brief overview is given of the procedures for preparing clean, well ordered surfaces of thin specimens suitable for UHV surface science with an electron microscope. Examples are presented of results from the gold (001) 5×20 reconstruction and the boron-doped Si(111)√3×√3R30° reconstruction. Results from the electron-beam-induced reduction of NiO in a controlled pressure of 1×10-7 Torr of Co are described which illustrated the critical role of background gases in electron microscopy.
