Researchers Identify Novel Topological Properties in Cobalt Disulfide


Researchers Identify Novel Topological Properties in Cobalt Disulfide
Written by AZoMDec 21 2020
The Schoop Lab, which is heading an association of institutions both in the United States and overseas, has reported unexpected new topological characteristics of cobalt disulfide (CoS
2) a magnetic pyrite expanding one’s interpretation of electrical channels in this

The researchers used ab-initio calculations and angle-resolved photoelectron spectroscopy and observed that bulk CoS
2 contains Weyl nodes. These Weyl nodes enabled the team to make predictions about the surface properties of this material.
Within its band structure, the material contains Weyl-fermions and Fermi-arc surface states, which may allow it to act as a platform for unusual phenomena and also places it among materials candidates for applications in spintronic devices. ....

Abstract:
Leading a collaboration of institutions in the U.S. and abroad, the Princeton University Department of Chemistry is reporting new topological properties of the magnetic pyrite Cobalt disulfide (CoS2) that expand our understanding of electrical channels in this long-investigated material.
