Material Coupling in Hybrid Neuromorphic Devices: From Fundamentals to System‐Level Applications

Advanced Functional Materials, EarlyView.
Hybrid neuromorphic devices utilize heterointerfaces between emerging semiconductors, where charge transfer and trapping, ion or defect modulation, and photogating are translated into synaptic functions. This paper discusses coupling strategies that tailor interfacial electronic and ionic properties in organic semiconductors, metal oxides, two ...

Orthogonal Passivation of Polar Facets for Efficient InSb Quantum Dot SWIR Photodetectors

Advanced Materials, EarlyView.
An orthogonal passivation strategy is developed for indium antimonide (InSb) colloidal quantum dots (CQDs): a metal halide passivates Sb‐terminated surface sites, while thiol ligands passivate In‐terminated sites. This site‐specific passivation reduces trap density, prolonging carrier lifetime and increasing carrier mobility, and enables InSb CQD ...

Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

Advanced Materials Technologies, EarlyView.
The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited
