[ Crystal Lattice (Real Space) ] │ ▼ (Fourier Transform via X-ray Diffraction) [ Reciprocal Lattice (Momentum Space) ] The Bragg and Laue Formulations
Define the transformation mathematically:
: This is an excellent starting point . The slides are directly linked from the official course page, organized by topic, and cover the core material from Kittel effectively. You can find them at the SIU physics department website.
Bragg’s law and Brillouin zones.
Use clean, sequential animations when deriving complex dispersion relations or solving the Kronig-Penney boundary conditions. Do not show the entire equation sequence at once.
Define the primitive translation vectors . A crystal lattice is mapped by are integers.
I can expand any module with specific derivations or lecture scripts to fit your goals. Share public link
The Fourier transform of the crystal. This is where we "live" when we talk about diffraction and wave vectors ( Update Note: Quasicrystals —structures that are ordered but not periodic. Slide 3: Crystal Binding (Chapter 3) Why does it stay together? Van der Waals: Fluctuating dipoles (Inert gases). Ionic/Covalent: Electron sharing and transfer. The "sea of electrons." Madelung Energy: The electrostatic glue in ionic crystals. Slide 4: Phonons I: Lattice Vibrations (Chapter 4-5) Elastic Waves: Quantizing sound as particles (Phonons). Dispersion Relations: The relationship between frequency ( ) and wave vector ( Acoustical vs. Optical Branches: How atoms move in sync vs. against each other. Thermal Properties: Heat capacity and the Debye Model at low temps). Slide 5: The Free Electron Fermi Gas (Chapter 6) The Drude-Sommerfeld Model: Treating electrons as a gas in a box.

A regular, periodic array of mathematical points in space.
. It bridges fundamental theory with the modern updates found in recent editions. Slide 1: Title & Overview
Treats the crystal as an elastic continuum, predicting that heat capacity drops off as T3cap T cubed near absolute zero ( ). This perfectly matches experimental results. 5. The Free Electron Fermi Gas
