If each atom or group of atoms is represented by a dot, or lattice point, and these points are connected, the resulting lattice may be divided into a number of identical ... WebNov 30, 2016 · To describe the geometry of crystals, so-called crystallographic axes are used. These axes define a three-dimensional coordinate system within the crystals' structure, and of course - as one would expect for describing three-dimensional bodies - there are 3 axes labeled a, b, and c.

WebThe ice crystal. The ice. crystal. At standard atmospheric pressure and at temperatures near 0 °C, the ice crystal commonly takes the form of sheets or planes of oxygen atoms joined in a series of open hexagonal rings. The axis parallel to the hexagonal rings is termed the c -axis and coincides with the optical axis of the crystal structure.

I'm confused about the crystal system of MoS2. In the case of the monolayer MoS2, it has 3-fold rotation symmetry when viewed from the top of its unit cell (c-axis). Even in the case of bulk (AB stacking) MoS2, it has only 3-fold rotation symmetry from the same direction. So, I expected that it must be the trigonal system. fztoWebSince the c-axis is also the optic axis in uniaxial crystals, light traveling along the c-axis will vibrate perpendicular to the c-axis and parallel to the ω refractive index direction.
