MSE PRO™ Chromium Thiophosphate (CrPS4) Crystal 2D Material

Among the many materials with 2D structures, the family of transition metal chalcogenophosphates (MPXn; where M = V, Cr, Mn, Fe, Co, Ni, Cu, Zn, or Cd, X = S, Se, or Te, and n=3 or 4) have 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.

Among various MPXn, Chromium Thiophosphate (CrPS4) is a promising antiferromagnetic material with a Neel temperature of 36 K in a bulk form. It exhibits an anisotropic magnetization behavior between the ab plane and c axis under the Neel temperature. CrPS4 also draws more attentions due to its semiconducting characteristics, as revealed by a temperature dependence of resistivity and optical band gap by the fundamental absorption edge at 1.4 eV. These properties make it a suitable candidate for optoelectronic devices and spintronic quantum information devices. As a layered material, intercalation behavior has been studied for LixCrPS4 in a perspective of possible use in batteries.
