MSE PRO Cobalt Phosphorus Sulfide (CoPS3) Crystal 2D Material

Among the many materials with 2D structures, the family of transition metal chalcogenophosphates (MPX3; where M = V, Cr, Mn, Fe, Co, Ni, Cu, Zn, and Cd and X = S, Se, and Te) has recently attracted the growing attention from the research community. This interest arises from its extensive variety of electronic properties. Thus, these materials exhibit a wide bandgap (up to 3.5 eV) that broadens their potential application in optoelectronics. In addition, some of these materials exhibit cooperative magnetic properties, in particular antiferromagnetism, which has been proven to persist even in the 2D limit. Interestingly, the reliance between the structural, electronic and magnetic properties boosts their potential in spintronics. Furthermore, these materials have also been studied as promising candidates for electrocatalytic applications.

As a representative MPX3, Cobalt Phosphorus Sulfide (CoPS3) is a quasi-two dimensional antiferromagnet on a honeycomb lattice with a Néel temperature of TN∼120K. It is shown to have XY-like anisotropy in its susceptibility. Its potential applications are antiferromagnetic storage devices, hydrogen evolution reaction and oxygen evolution reaction catalysts and high-performance spintronics.
