Two-dimensional Dirac fermions in bulk crystals

Abstract:

Dirac fermions have attracted great interest in recent years, as seen on the examples of materials like graphene and topological insulators [1-2]. In this talk, I will discuss quantum
transport in single crystals of (Sr,Ca)MnBi2 and similar materials [3-4]. The results demonstrate the existence of two dimensional Dirac fermions in bulk crystals with bismuth or antimony
square nets and show that such states are highly relevant for thermoelectric performance [5-7].
