referat pt.:
Topological semimetals among half-Heusler rare-earth bismuthides and other compounds
wygłosi
Instytut Niskich Temperatur i Badań Strukturalnych PAN
Physicists’ understanding of the importance of topology in electronic structure and electronic properties has initiated extensive research initially focused on topological insulators. Soon it occurred that the most of real bulk topologically non-trivial materials are semimetals. They form larger and more diverse family than topological insulators. Often compounds theoretically predicted to be topological insulators are topological semimetals, displaying substantial carrier concentrations. In this talk I will present our research on such materials, mainly, but not only, half-Heusler phases, discussing possible origins and apparent consequences of their semi-metallicity. I will concentrate on magnetotransport properties, often reflecting topological nature.
