Novel Optoelectronic Reconfigurable Transistors Based on Graphene/VO2 Heterojunction for Efficient Neuromorphic Perception, Computation, and Storage

open access: yesAdvanced Science, EarlyView.
A novel optoelectronic reconfigurable neuromorphic transistor based on a graphene/VO2 heterojunction with inserted Au electrodes is proposed. It exhibits broad‐spectrum self‐powered photodetection capability ranging from 365 to 940 nm. Through bias control and electrode sizing strategies, multiple functions for switch, synapse, and storage are achieved,

Anisotropic Charge Diffusion in Polar‐Layered Oxides for Ultralong Charge Retention

open access: yesAdvanced Science, EarlyView.
Anisotropic charge diffusion in epitaxially grown LAO thin films is reported, which enables ultralong charge retention. Surface‐accumulated oxygen vacancies effectively suppress out‐of‐plane electron hopping, allowing ≈90.9% of the surface charges to remain after a few weeks or longer.

Exploration of Quasi‐Direct Band Edge in a Multilayer Ferroelectric Semiconductor for Applications in Van Der Waals Stacked Heterojunction Solar Cell and Photocatalytic Devices

open access: yesAdvanced Science, EarlyView.
Multilayered AgBiP2Se6 has been systematically characterized to be a quasi‐direct semiconductor using theoretical calculations and optical experiments. It possesses an indirect bandgap of 1.46 eV and a direct gap of 1.535 eV for simultaneously absorbing the NIR to visible‐light photons. In combination with a p‐type Ga0.5In0.5Se, a high efficiency p‐Ga0.

Tailored Stitching and Vertical Stacking for High‐Voltage Multifunctional Structural Batteries with Enhanced Electrochemical–Mechanical Coupling

open access: yesAdvanced Science, EarlyView.
A stitched, vertically stacked CFRP structural battery uses Kevlar interlaminar threads and selective PP/Elium® thermoplastics to maintain tight electrode spacing and robust electrolyte wetting. The architecture sustains electrochemical performance under bending and delivers higher pack voltage via through‐thickness series connections without ...
