[institut] seminar Centra za fiziku čvrstog stanja i nove materijale

[Zoran Popovic]

Poštovane koleginice i kolege,

U ponedeljak 14.jula u 14.00 u čitaonici bilblioteke IF-a Prof. dr 
Cedomir Petrović, Condensed Matter Physics, Brookhaven National 
Laboratory
održaće seminar po naslovom:


Two-dimensional Dirac fermions in bulk crystals


Rezime:

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].
