Crystallographic planes examples
WebDear students our today's lecture will focus on the crystallographic points directions and planes Essentially we will talk about how to quantitatively describe a crystal structure We will first start from point coordinates how to describe a point position in the crystal structure For example if you have a unit cell characterized by this a, b and c which are unit cell … http://www.clay.uga.edu/courses/3010/3010lecture06.html

WebThis coordinate system is based on the 3-axis Miller index, but with an extra axis which is used for hexagonal crystals. The system can indicate directions or planes, and are often written as (hkil). Some common examples of Miller Indices on a hexagonal prism include , the body diagonal; , the face diagonal, and , the face plane. http://calistry.org/calculate/latticePlanesMillerIndices

Set of directions or axes equivalent to [ hkl] under the symmetry group of the crystal; a direction or axis in the set. For example, in a cubic crystal the〈100〉 directions are [100], [010], [001], [ ¯. ¯1 ]. Plane; set of parallel planes.
