Crystal planes and directions
WebCrystallographic directions and planes are important in both the characteristics and the applications of semiconductor materials since different crystallographic planes can exhibit significantly different physical properties.For example, the surface density of atoms (atoms per square centimeter) can differ substantially on different crystal planes.A standardized … WebThe Face-Centered Cubic (FCC) unit cell can be imagined as a cube with an atom on each corner, and an atom on each face. It is one of the most common structures for metals. FCC has 4 atoms per unit cell, lattice constant a = 2R√2, Coordination Number CN = 12, and Atomic Packing Factor APF = 74%. FCC is a close-packed structure with ABC-ABC ...

WebSep 8, 2024 · In crystallography, we use Miller indices to specify locations, directions, and planes in a crystal. Standard \(\mathrm{x}-\mathrm{y}-\mathrm{z}\) Cartesian coordinates use a basis consisting of three orthogonal axes in three dimensions with unit length. In Miller index notation, we will rely on the lattice vectors of the unit cell as our basis. billy pavliska waco txWebMiller indices plot a direction or plane along 3 axes that correspond to the 3 lattice parameters of the crystal.
