Optical Properties of Solids

Perex

The 12 lectures follow the textbook by Mark Fox “Optical Properties of Solids”, with additional materials by the instructor to make the lectures more self-contained, especially for scientists from other disciplines.

They cover the basic theory for transmission and reflection of light based on Maxwell’s equations and the optical properties of metals and insulators using the Drude and Lorentz oscillator models for electrons and phonons, which form the basis of ellipsometry data analysis. Then they move on to describe infrared lattice absorption, interband absorption in semiconductors, the excitonic enhancement of these transitions due to electron-hole interaction, photoluminescence, and finite-size quantum effects leading to a blueshift of the optical spectra in confined systems. Mathematical formalisms are kept to a minimum. Instead, the focus is on concepts, graphs and figures, and the interpretation of optical spectra.

Dr. Stefan Zollner is the Academic Department Head and Professor of the Physics department at the New Mexico State University in Las Cruces, USA. He joined us for 6 months as part of the Mobility Project that is supported by ESIF and MEYS.
