DeScription:

  SnPSe₃ is a layered crystal belonging to the metal selenophosphites family of van der Waals crystal. They assume the chemical formula of MPSe₃ with M=Sn. It has been shown that SnPSe₃ crystals have ~1.49 eV optical band gap which suitably falls within the visible spectra. They have been used mainly for 2D catalysis but their quantum properties in the monolayer or few-layer form still remains unknown. Our SnPSe₃ crystals have been synthesized using modified Bridgman technique to achieve 99.9995% or higher purity and these crystals exhibit remarkable exfoliation characteristics. Our growth method has been optimized to eliminate commonly found SnSe, SnSe₂, and Sn2Se₃ phases. So we guarantee 100% single SnPSe₃ crystals. Samples come ready for exfoliation without any need for further treatment.
