Formation of Light‐Emitting Defects in Ag‐Based Memristors

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
How does a memristor begin to emit light‐before it even conducts? This work reveals that nanoscale silver clusters form, diffuse, and aggregate during activation, driving early photoluminescence ahead of current flow. Linking these precursor dynamics to later electroluminescence, it uncovers the origins of light emission and enables precise control of ...

Bi‐Functional Single‐Crystalline Active Layers for Uniform Area‐Emitting Organic Light‐Emitting Transistors

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
This work employs monolayer molecular crystals (MMCs) as bi‐functional active layers in organic light‐emitting transistors (OLETs). Thanks to the efficient horizontal hole transport and vertical hole injection, the OLETs show a high mobility of 6.64 cm2V−1s−1 and exhibit uniform area emission.
