VOx‐Based Non‐Volatile Radio‐Frequency Switches for Reconfigurable Filter

Advanced Science, EarlyView.
Vanadium oxide‐based memristor devices achieve high performance for next‐generation non‐volatile memory and RF switches. These devices demonstrate a cutoff frequency of ≈4.5 THz, low insertion loss (<0.46 dB), and high isolation (>20 dB) from 0.1 to 20 GHz with stable operation extended to 67 GHz.

Phosphorus Vacancy‐Induced Built‐In Electric Field for Electromagnetic Properties Modulation

Advanced Science, EarlyView.
The advantages of defect‐induced polarization resulting from group VA anion vacancies, particularly phosphorus vacancies (VP) are analyzed in comparison to the anion vacancies of other elements. P atoms possess both plentiful high‐energy unpaired valence electrons in 3p orbitals and moderate nonmetallicity, thus the selection of VP for regulating EM ...

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

Advanced 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 ...
