Ferroelectricity
What is Ferroelectricity? Ferroelectricity is a property of certain nonconducting crystals, or dielectrics, that exhibit spontaneous electric polarization (separation of the centre of positive and negative electric charge, making one…
Laue’s Experiment
Laue’s Experiment Von Laue, in 1913, suggested that a crystal can act as a three dimensional grating for an X-ray beam. The experimental arrangement used to produce diffraction in…
Crystal-System Structure
The Seven Crystal Systems Triclinic System: All three axes are inclined towards each other, and they are of the same length. Based on the three inclined angles the various forms…
Seven Crystal Systems and Fourteen Bravais Lattices
What are Crystal Systems? In a crystal system, a set of point groups and their corresponding space groups are assigned to a lattice system. Of the 32 point groups that…
