Magnetic semiconductor FePS₃ has a monoclinic structure with the factor group C_2h. The crystal has been synthesized through chemical vapor transport (CVT) or flux transport technique (similar to CVT except chemical transport agent is not utilized to attain high crystallinity and purity) with confirmed 99.999% purity and high crystallinity. Each crystal measures ~1cm in size, perfect 0001 direction oriented. To date, FePS3 has been reported to have 1-1.5 eV optical band gap, its material properties in the monolayer limit remain large unexplored.
