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.
