Extended Data Fig. 9

a, This technology can be applied to multi-layer stacking by sequential coating over universal substrates without surface treatment, and the coated film can be transferred to the desired substrate through a release strategy. For examples, b, device structure of an Al2O3-gated IGZO transistor prepared by sequential coating of each metal precursor and c, its transfer curve. d, Transfer-printed halide perovskite (MAPbI3) film over a transparent PET film and e, its optical properties.
