“…21 In addition, strained SnIP can achieve highly tunable polarization after absorbing water molecules. 22 Besides, SnIP nanorods can be easily exfoliated due to the weak vdW interactions, and isolated one-dimensional (1D) double-helix strands have been obtained in SnIP@C 3 N 4 (F,Cl) heterostructure systems or in carbon nanotubes. 23 With the unique structure and properties, quasi-1D semiconductor SnIP has shown great promise for next-generation applications like flexible devices and mechanical sensors.…”
