Marder 1 (Crystals) Flashcards
What is crystalline order?
simplest arrangement atoms can take ti form a macroscopic solid
What makes a compound allotropic?
They have more than 1 crystalline stable form given a pressure and temperature
What is a crystal?
A solid where the atoms are arranged in the form of a lattice
what is a lattice?
Arrangement of points that repeats a pattern over and over again
What is the Bravais lattice?
Is the simplest kind of lattice where the neighborhood of every point in the lattice is the same
What is a lattice with a basis?
Bravaiss lattice to which identical assemblies of points have been added to every lattice
What is the primitive unit cell?
Small region of space from which the full information of the crystal can be obtained
How do you build the Wigner-Seitz cell?
Draw a line of a given point to its closest neighbors and then split those lines with perpendicular lines. the figure resulting of the second set of lines intersecting will provide the cell
