Single-Electron Charging in Phosphorus Donors in Silicon Observed by Low-Temperature Kelvin Probe Force Microscope

Single-Electron Charging in Phosphorus Donors in Silicon Observed by Low-Temperature Kelvin Probe Force Microscope
Kelvin probe force microscopy (KFM) working at low temperatures (13 K) is used to study local electronic potential fluctuations induced by individual phosphorus donors. Electronic potential maps were measured at the surface of thin phosphorus-doped channel of silicon-on-insulator field-effect transistors for different values of backgate voltage.

Buoyancy‐Driven Flotation and Magnetotaxis of Vesicle‐Based Prototissue Fibers Induced by Oxygen Bubbles under Enzymatic Reactions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
We demonstrate new strategies to induce motility of vesicle‐based prototissue fibers by generating oxygen bubbles under an enzymatic reaction. The prototissue fibers exhibited flotation due to the buoyancy of oxygen bubbles and magnetotaxis due to the paramagnetic property of oxygen.

Fabrication of Multifunctional FeSi Gyroid Lattice Composites via Additive Manufacturing and Polymer Infiltration

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
A two‐step approach combining laser powder bed fusion of FeSi electrical steel with Bakelite infiltration enables the fabrication of multifunctional gyroid lattice composites. The resulting structures exhibit high strength, magnetic anisotropy, and complete polymer infiltration, demonstrating a simple and scalable route toward lightweight, mechanically

Complementary Logic Driven by Dielectrophoretic Assembly of 2D Semiconductors

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Scalable, parallel fabrication of complementary logic gates is demonstrated using electric‐field‐driven deterministic assembly of electrochemically exfoliated 2D n‐type MoS2 and p‐type WSe2 nanosheets. This strategy yields MoS2 and WSe2 transistors featuring average mobilities of 4.3 and 3.0 cm2 V−1 s−1, respectively, and on/off ratios of > 104 ...

Truncated Conjugate Structure Improves Solar‐Driven Hydrogen Peroxide Production Catalyzed by Benzobisthiazole‐Based Conjugated Polymers

Advanced Science, Volume 13, Issue 7, 3 February 2026.
In this work, a novel molecular design strategy was employed to truncate large‐scale conjugated structures in covalent polymer materials. This approach significantly enhances the catalyst’s light‐harvesting capability, prolongs the lifetime of photogenerated charge carriers, and improves catalytic activity, thereby offering a new conceptual pathway for

Modeling and Measurement of Noise in Aluminium Nitride Piezoelectric MEMS

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
This work analyzes electrical noise in piezoelectric AlN MEMS devices using a combined measurement‐modeling approach. The framework separates sample and amplifier noise contributions and demonstrates close agreement between model and experiment at both room and cryogenic temperatures.
