X-ray crystallography has provided the crystal type and lattice dimensions for numerous solids. In this technique, high-energy x-rays strike the crystal and are diffracted in a pattern characteristic of the particular lattice type. Complex mathematical... 

Determination of lateral periodicities in the self-assembled layer is an important goal in surface analysis. 2D surface crystal structures are best studied with low energy electrons, since their escape depth, contrary to X-rays, is basically limited to the top-most atomic layers. Consequently, LEED has become the most important method in surface monolayer crystallography. However, single-crystalline substrates are required. Via this technique, 2D supramolecular chiral lattice structures on single crystal surfaces had already been observed in 1978 [19]. 

X-ray crystallography has provided the crystal type and lattice dimensions for numerous solids. In this technique, high-energy x-rays strike the crystal and are diffracted in a pattern characteristic of the particular lattice type. Complex mathematical analysis can convert the diffraction pattern to the actual crystal structure. Advances in computer technology have revolutionized this field in the past few years. Complex structures, formerly requiring months or years to determine, can now be analyzed in short order. Even huge protein and nucleic acid chains can be woiked out by the crystallographer. ...
