Two-dimensional (2D) layered semiconductors reveal boundless potential in next-generation ferro-, piezo-, and pyroelectric property-based self-powered devices. In this scenario, we report the experimental observations, which are consistent with first-principles calculations of out-of-plane ferro- piezoelectricity 2D tin selenide (SnSe) van der Waals-bonded monolayers. It has a strain-engineered, synergetic trigonal crystal structure. Thin 2D-SnSe nanosheets few monolayers exfoliated from bulk orthorhombic SnSe, facilitates enormous pyroelectric-aided transient thermal energy harvesting. particular, phase amplitude hysteresis piezoresponse force microscopy affirms that trilayer SnSe exhibit profound piezoelectric (d33 ∼ 3.45 pm/V) responses. A robust response persists figure merit (Fv 8 m2 C-1 FD 132 × 10-6 Pa-1/2), an order higher than commercially benchmark pyroelectrics. Hence, layers could be promising materials for pyroelectric-based waste heat scavenging, infrared imaging, detectors various applications.
