Cu₂O Thin Films: The Role of Humidity in Tuning the Texture and Electrical Properties of Cu₂O Thin Films Deposited via Aerosol‐Assisted CVD (Adv. Mater. Interfaces 3/2019)

The image shows a substrate coated with a Cu2O thin film (in red) deposited by chemical vapor deposition. The shape and orientation of the Cu2O crystals depend on whether the film is deposited in dry (sunny) or wet (rainy) conditions. The SEM image in the inset shows an example of the Cu2O cubes obtained with wet conditions. More details are in article number 1801364 by Hongjun Liu, David Muñoz-Rojas and-co-workers.
