Positive Feedback Organic‐on‐Silicon Upconversion Devices

Advanced Science, EarlyView.
Positive optoelectronic feedback is achieved by depositing a tandem OLED on top of a heterojunction Si photodiode. The resulting hybrid device is bistable and upconverts near‐infrared light (λ = 1050 nm) to visible light (λ = 570 nm) with a photon‐to‐photon upconversion yield of up to 900%.

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains

Advanced Science, EarlyView.
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Broadband All‐Optical Memtransistor Based on Organic Cocrystals for Noise‐Robust Motion Recognition

Advanced Science, EarlyView.
This work presents an all‐optical synaptic transistor using DTT‐TCNQ organic charge transfer cocrystals, achieving broadband bidirectional modulation (395–808 nm) with highly linear synaptic plasticity (nonlinearity coefficients αp = 0.00191, αd = 0.00305).
