The scalable processing of two-dimensional (2D) semiconductor thin films and superlattices with precisely controlled layer thickness is crucial for the widespread adoption of 2D semiconductors in electronics and optoelectronics. In the May issue of Chem, Xue et al. introduced a meticulous method for producing high-quality photoluminescent 2D semiconductor monolayer inks. They demonstrated the fabrication of not only semiconductor thin films with precisely controlled layer number but also hybrid superlattice thin films with bright visible-light emission through a solution-processable assembly technique.
