Optical Properties of Nanomaterials 03: Lorentz model of the dielectric function

Lecture by Nicolas Vogel. This course gives an introduction to the optical properties of different nanomaterials. We derive fundamental relations describing the interactions between materials and electromagnetic radiation and discuss the resulting optical properties for dielectric, metallic and semiconducting particles.

This chapter derives the Lorentz model of the dielectric function for dielectric materials. We investigate the atomic origins of the interaction of light with matter to derive an expression for the dielectric function by connecting with macroscopic properties. We learn about the frequency-dependent nature of the refractive index and discuss different resonances that can be excited within dielectric materials.
