Superlattice Engineering on 2D Bi2Te3‐Sb2Te3 Chalcogenides

open access: yesAdvanced Science, EarlyView.
This study presents an innovative approach to fabricating 2D Bi2Te3‐Sb2Te3 chalcogenide superlattices in wrapped, lateral, and vertical configurations. Utilizing a novel precursor switching method, chemical vapor deposition, and post‐growth techniques, the research achieves controlled superlattices with sharp interfaces.

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Superconducting Carbon‐Cage Network with Tc of 109 K at Ambient Pressure

open access: yesAdvanced Science, EarlyView.
By introducing elemental and hole doping into a theoretically designed sp3‐hybridized C18 carbon cage, superconductivity with a transition temperature up to 109 K is predicted under ambient pressure. These findings offer a promising pathway for designing high‐Tc superconductors based on stable covalent carbon frameworks.

High‐Throughput MicroED for Probing Ion Channel Dynamics

open access: yesAdvanced Science, EarlyView.
High‐throughput MicroED offers a new approach for visualizing ion channel dynamics. This approach reveals NaK’s sodium binding modes and NaK2CNG’s potassium‐induced selectivity filter dilation and gating. By capturing these distinct structures, this work challenges traditional models of ion channel permeation and selectivity. Abstract Ion channels play

A Large Area Hybrid Phototransistor Platform with Large Detectivity and Fast Response to NIR Light

open access: yesAdvanced Electronic Materials, EarlyView.
A geometrically engineered tri‐channel architecture with a 4‐mm2 large sensing area is implemented in a hybrid multilayer phototransistor. The side channels electrically coupled to the 4 mm2 large central area enable efficient and fast detection of small perturbations of the charge density at the sensing surface, produced by a near‐infrared ...
