Description
This course presents the physical properties of different nanostructures such as quantum wells, 1D photonic crystals, carbon nanotubes or graphene. Electronic (structure and transport), vibrational and optical properties are discussed as well as radiation-matter interaction.
The aim is to describe the elaboration of low dimensional materials, the associated electronic, photonic and phononic structures, to study the transport phenomena, the electron-photon and electron-phonon couplings, the excitons as well as the absorption, emission and diffusion of light.
Objectives
Describe physical phenomena occurring at the nanoscale and understand the properties of nanomaterials.
Necessary pre-requisites
Crystallographic concepts, reciprocal lattice. Band structure. Propagation of electromagnetic waves (Maxwell's equations). Vibrations of a crystal, absorption and dispersion of light.
Recommended Prerequisites:
Excitonic effects, electronic and phononic dispersion curve.
Knowledge control
Continuous assessment.
4 written and 1 oral exam.
The final grade is the average of the 5 grades.
