Low-Temperature Centimeter-Scale Growth of Layered 2D SnS for Piezoelectric Kirigami Devices
Tin monosulfide (SnS) is a promising piezoelectric material
with
an intrinsically layered structure, making it attractive for self-powered
wearable and stretchable devices. However, for practical application
purposes, it is essential to improve the output and manufacturing
compatibility of SnS-based piezoelectric devices by exploring their
large-area synthesis principle. In this study, we report the chemical
vapor deposition (CVD) growth of centimeter-scale two-dimensional
(2D) SnS layers at temperatures as low as 200 Ā°C, allowing compatibility
with processing a range of polymeric substrates. The intrinsic piezoelectricity
of 2D SnS layers directly grown on polyamides (PIs) was confirmed
by piezoelectric force microscopy (PFM) phase maps and forceācurrent
corroborative measurements. Furthermore, the structural robustness
of the centimeter-scale 2D SnS layers/PIs allowed for engraving complicated
kirigami patterns on them. The kirigami-patterned 2D SnS layer devices
exhibited intriguing strain-tolerant piezoelectricity, which was employed
in detecting human body motions and generating photocurrents irrespective
of strain rate variations. These results establish the great promise
of 2D SnS layers for practically relevant large-scale device technologies
with coupled electrical and mechanical properties
