Janus ferroelastic ScS 2 M monolayers: switchable highly anisotropic, piezoelectric, optoelectronic, and photocatalytic properties

Gui-Yuan Luo, Xiao Jia, Wu-Ming Liu, Jia-He Lin, Tian Zhang

Ferroelastic switching enables nonvolatile reorientation of piezoelectric and optoelectronic anisotropies in Janus TP/HP ScS 2 M (M = P, As, Sb), offering opportunities for vector sensing, memory, and strain-tunable photocatalytic water splitting.
