A flash-evaporation printing technology is developed that employs freestanding carbon nanotubes as a flash evaporator. The target materials precoated on the flash evaporator are printed onto substrates by gas-phase transportation. This methodology offers a printable solution for hybrid perovskite thin films, and can also be used to print patterns and a wide variety of materials on large panels.
