Research article demonstrates a hybrid liquid metal cathode enhancing device efficiency in stretchable OLEDs, suggesting improved application potential.
Stretchable Organic Light-Emitting Diodes The cover depicts intrinsically stretchable light-emitting diodes with hybrid liquid metal cathodes. In their Research Article (DOI: 10.1002/adma.202518254), Wei Liu, Sihong Wang, Himchan Cho, and co-workers present a hybrid liquid metal cathode that combines the advantages of bulk liquid metal and liquid metal particles in a bilayer architecture. This hybrid cathode facilitates efficient electron injection, enabling high luminance and device efficiency along with low driving voltages.
