ICDIM-2024 International School-Seminar,targeted for young researchers (PhD students, post-docs, junior assistant researchers…), focuses on nanostructuring of materials by swift heavy ions. The program of School includes lectures on utilization of ion beams for fabrication and modification of nanostructures in insulators and non-metallic materials. The School will cover the range of topics such as the irradiation effects and properties of defects in nanomaterials and relevant instrumentation and methodologies.

Nano- and micro- scale thermal transport and mechanical properties of irradiated materials
Prof. Zhandos Utegulov Nazarbayev University, Astana, Kazakhstan
Review of Radiation Damage and Basic Properties of Point Defects in Wide-Band Gap Metal Halides, Oxides and Perovskites
Dr. Anatoli I. Popov Institute of Solid State Physics, University of Latvia, Riga, Latvia
I will present an update survey of the optical properties of primary radiation-induced point defects in alkali halides, binary oxides and also some oxide and halide perovskites. We will discuss in details the optical properties of single electron F and F+ centers in rock-salt (fcc) alkali halides and oxides and show how that the Mollwo-Ivey law, well-known for the F-type centers in alkali halides, may be extended for other rock-salt insulators. We will also discuss the major differences in point defect production mechanisms in halides and oxides. We will see how the Rabin-Klick diagram may be generalized for a whole family of alkali halides. We will discuss also the correlation between the temperatures at which hole polarons start migration in a series of alkali halides (fluorites, chlorides, bromides, iodides) and the appropriate lattice parameters. Finally, the F-type center migration and aggregation into metal colloids in alkali halides and oxides will be also discussed. Special attention will be paid to a detailed comparison of diffusion-controlled F center thermal annealing in neutron, electron and heavy-ion irradiated materials.
