Sub-nanosecond signal propagation in anisotropy engineered nanomagnetic logic chains [PDF]

, 2014
Energy efficient nanomagnetic logic (NML) computing architectures propagate and process binary information by relying on dipolar field coupling to reorient closely-spaced nanoscale magnets. Signal propagation in nanomagnet chains of various sizes, shapes,

Enhanced Switching Performance in Single‐Crystalline PbTiO3 Ferroelectric Memristors for Replicating Synaptic Plasticity

Advanced Functional Materials, EarlyView.
This study demonstrated single‐crystalline PbTiO3‐based memristors with atomically sharp interfaces, well‐ordered lattices, and minimal lattice mismatch. The devices exhibited an ON/OFF ratio exceeding 105, high stability, and rich resistance‐state modulation.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Nanofabrications of T shape gates for high electron mobility transistors in microwaves and THz waves, a review

Micro and Nano Engineering, 2021
High electron mobility transistors (HEMTs) are the basic building block in microwave monolithic integration circuits (MMICs) for broad applications in micrometer (0.3–100 GHz), millimeter (100–300 GHz) and tera [1] hertz (300 GHz–10 THz) wave.

Submicrosecond X-ray lithography

Electronics Letters, 1978
X-rays from laser-heated plasmas were used to replicate features as fine as 750 nm in the positive resist polybutene-1-sulfone (p.b.s.). The measured sensitivities of p.b.s. to pulsed and d.c. X-rays (≈ 109 ratio in exposure rate) are similar (no reciprocity loss). Laser-plasma X-rays produced only small (0.25 V) flat-band shifts in m.o.s.

Magnifying perfect lens and superlens design by coordinate transformation [PDF]

, 2007
The coordinate transformation technique is applied to the design of perfect lenses and superlenses. In particular, anisotropic metamaterials that magnify two-dimensional planar images beyond the diffraction limit are designed by the use of oblate ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...
