m TED can be used for surfaces although it is a specialized technique. There is also profile imaging. |

'''Reflection high-energy electron diffraction''' ('''RHEED''') is a [[analytical technique|technique]] used to characterize the surface of [[crystalline]] materials. RHEED systems gather information only from the surface layer of the sample, which distinguishes RHEED from other [[material characterization|materials characterization]] methods that also rely on diffraction of high-energy [[electrons]]. [[Transmission electron microscopy]], another common [[electron diffraction]] method samples mainly the bulk of the sample due to the geometry of the system, although in special cases it can provide surface information. [[Low-energy electron diffraction]] (LEED) is also surface sensitive, but LEED achieves surface sensitivity through the use of low energy electrons.
