2D Programmable Photodetectors Based on WSe2/h‐BN/Graphene Heterojunctions

Advanced Science, EarlyView.
A programmable non‐volatile bipolar semi‐floating gate photovoltaic photodetector is developed, enabling reversible light response switching and improved response speed. This capability facilitates the successful implementation of the device in dual‐channel optoelectronic hybrid communication, fulfilling the performance demands of high‐speed, large ...

Agile Free‐Form Signal Filtering and Routing with a Chaotic‐Cavity‐Backed Non‐Local Programmable Metasurface

Advanced Science, EarlyView.
A multi‐parameter‐tunable, all‐metallic, low‐loss, wave‐chaotic cavity enables a frequency‐insensitive (over a 7 GHz bandwidth) technique to synthesize desired transfer functions within smaller windows to high accuracy and with complete reconfigurability of shapes and center frequencies.

Low‐Frequency Noise Spectroscopy for Navigating Geometrically Varying Strain Effects in HfO2 Ferroelectric FETs

Advanced Science, EarlyView.
This study investigates the material and geometrically varying strain effects on HfO2 ferroelectric FETs (FeFETs). Through noise analysis, the reverse scaling effect is demonstrated due to the strain effects in the FeFET structure. This result indicates the importance of strain engineering in the FeFET for optimized performance.

Thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer architectures

Aggregate, Volume 3, Issue 6, December 2022., 2022
We report a thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer (CSP) architectures wherein supramolecular graft polymer (SGP) transforms into supramolecular polymer network (SPN) based on collaborative dynamic covalent bond chemistry and host−guest chemistry.

Carry Trades and Global FX Volatility [PDF]

We investigate the relation between global FX volatility and the excess returns to carry trade portfolios. We find a significantly negative return co-movement of high interest rate currencies with global volatility, whereas low interest rate currencies ...

Overcoming Extreme Ammonia Inhibition on Methanogenesis by Artificially Constructing a Synergistically Community with Acidogenic Bacteria and Hydrogenotrophic Archaea

Advanced Science, EarlyView.
This study proposes a two‐step biological strategy to synergistically enhance the three stages of anaerobic digestion, ultimately eliminating the extreme ammonia inhibition and breaking through the inefficiency bottleneck of conventional biotechnology.
