Synopsis:

This course provides an overview of point defects and their properties in solids, including crystals and glasses (also micro- and nanoscale materials), and introduces the basic principles of point defect engineering for improving the physical properties of materials. The properties of color centers and the peculiarities of their formation are explained in detail, including activation energies to assess their localization in 3D, 2D, 1D, and 0D materials. These include trapping centers such as shallow and deep hole and electron traps of O-, Vk, O2-, F and F+ centers, etc. The local structure and the influence of other defects, both internal and external, as well as the location in the crystal lattice or position in the glasses on the thermal stability of the mentioned trapping centers are discussed. The course also includes an introduction to the basic principles of efficient techniques suitable for the study of physical processes associated with the formation of various types of defects. These include in particular electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR) and thermally stimulated luminescence (TSL). The subject also gives an overview of other techniques based on the use of X-ray and electron beam.

Requirements:

Basic knowledge of group theory, solid state physics and quantum mechanics

Syllabus of lectures:

Application of electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR) and thermally stimulated luminescence (TSL) techniques. In addition, other techniques based on the use of X-ray and electron beam are discussed. The properties of color centers and peculiarities of their formation are explained in detail, including the activation energy to determine their localization in 3D, 2D, 1D and 0D materials.
