Digital Electrochemistry: Digital Electrochemistry for On‐Chip Heterogeneous Material Integration (Adv. Mater. 26/2021). Issue 26 (1st July 2021) - Bao, Bin
Abstract : In article number 2101272, Bin Bao, Daniil Karnaushenko, Oliver G. Schmidt, and co‐workers develop a digital electrochemistry approach for on‐chip heterogeneous material integration. An amorphous indium‐gallium‐zinc oxide thin‐film‐transistor (a‐IGZO TFT) active‐matrix is used to address pixels within the matrix and locally control electrochemical reactions for material growth and actuation. Multicolored electrochromic patterns and actuator arrays can be fabricated. The approach can be extended to a broad range of materials and structures, opening up a new path for advanced heterogeneous microsystem integration.
