Abstract
Atomically thin, mechanically flexible, memory-functional, and power-generating crystals play a crucial role in the technological advancement of portable devices. However, the adoption of these crystals in such technologies is sometimes impeded by expensive and laborious synthesis methods, as well as the need for large-scale, mechanically stable, and air-stable materials. Here, an instant-in-air liquid metal printing process utilizing liquid bismuth (Bi) is presented, forming naturally occurring, air-stable, atomically thin, mechanically flexible nanogenerators and ferroelectric oxides. Despite the centrosymmetric nature of the monoclinic P21/c system of achieved α-Bi2O3-δ the high kinetics ..
