“…Nowadays, research on two-dimensional (2D) piezoelectric materials is advancing rapidly. 2–7 For example, both theoretical and experimental studies have consistently demonstrated the piezoelectric properties of MoS 2 monolayer and h-BN. 8–10 Other 2D materials, such as TMDC, 11 group-IV monochalcogenides, 12 and group-III monochalcogenides, 13 have been predicted to possess intrinsic in-plane piezoelectric properties, albeit with relatively small piezoelectric coefficients.…”

“…Since the report of the piezoelectric effect in 1880, piezoelectric materials with the ability to convert mechanical energy into electrical energy have undergone rapid development and have been widely used in various nanoscale sensors, energy harvesters, mechanical actuators, and acoustic storage devices. At present, the commonly used bulk piezoelectric materials include α-quartz ( d 11 = 2.27 pm/V) and wurtzite AlN ( d 33 = 5.4 pm/V), and another traditional type is lead-based material represented by Pb­[Zr x Ti 1– x ]­O 3 (PZT). , All of them more or less suffer from the drawbacks of toxicity (lead element), high cost, and high dielectric constant. In addition, traditional bulk piezoelectric materials are deficient in high crystallinity and high integration, , which cannot meet the requirements of constructing electronic devices toward the nanoscale in the future.…”

“…2D materials with Janus geometry have garnered much attention for their new properties arising from the broken out-of-plane symmetry. 10,15–24 Interestingly, Yang's group has proposed a new photocatalytic model with an intrinsic dipole that can relieve restriction on the bandgap requirement of photocatalysts. 25 The potential applications of Janus materials in photocatalysis have been revealed in the past.…”
