Microreactor‐Assisted Soft Lithography for Rapid and Inexpensive Patterning of Nanostructured ZnO/CuO Heterojunctions

Microreactor‐Assisted Soft Lithography In article number 2401112, Chih‐hung Chang and co‐workers demonstrate a novel microreactor‐assisted soft lithography process to deposit nanostructures with multiscale 3D geometric shapes and fabricate p‐n heterojunction with n‐type ZnO and p‐type CuO. Factors determining the printing process are studied based on COMSOL simulation and experimental results. This novel process enables the scalable fabrication of complicated functional nanostructures on the desired regions using low‐cost and facile solution‐based methods.
