Reflection high energy electron diffraction (RHEED) and its extension, reflection electron microcsopy (REM) have been used extensively for studying the atomic structure of crystal surfaces. The Important features of REM are that surface steps as low as one atom high can be observed in real space with strong contrast and high spatial resolution. Other surface structures such as reconstructions, dislocations, stacking faults, etc., have also been observed on surfaces of bulk crystals with minimal preparation.
