Solid state physics (or condensed matter physics) is one of the most active and versatile branches of modern physics that have developed in the wake of the discovery of quantum mechanics. It deals with problems concerning the properties of materials and, more generally, systems with

Bachelors thesis in Keywords: graphene, tight binding, electron-phonon coupling, solid-state physics 6 2.1.3 Bloch's Theorem and the Electron's Total Wave Function . av A Börjesson · 2010 · Citerat av 1 — depending on the level of physics included in the description. For periodic solids, Bloch's theorem states that the eigen functions for the Kohn-Sham equation introduction to the physics of crystalline solids for electrical engineers dr. ir.

to produce the familiar band gaps, semiconductors, and so on, of solid-state physics. The study of photonic crystals is likewise governed by the Bloch-Floquet theorem, and intentionally introduced defects in the crystal (analo-gous to electronic dopants) give rise to localized electromagnetic states: linear waveguides and point-like cavities.
