Role of the Recombination Zone in Organic Light‐Emitting Devices
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

A Perspective on SOI Symmetric Lateral Bipolar Transistors for Ultra-Low-Power Systems
The reasons why state-of-the-art vertical bipolar circuits dissipate very high power are explained. The recent advent of SOI symmetric lateral bipolar transistors invites us to rethink bipolar as a high-speed but low-power technology.

A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.
