Tunable Patterned Blue Phase Liquid Crystals Based on Lithographic Process Technology

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A patterned blue phase liquid crystal device with electrically driven, localized bistability is demonstrated using a cost‐efficient photolithographic dual‐alignment process. The device switches between a high‐contrast patterned state and a uniform reflective state.

Is There A Pure Electronic Ferroelectric?

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Screw‐Dislocation‐Engineered Quantum Dot: Geometry‐Tunable Nonlinear Optics, Orbital Qubit Addressability, and Torsion Metrology

Annalen der Physik, Volume 538, Issue 2, February 2026.
A uniform torsion field—representing a controlled density of parallel screw dislocations—confines a single electron into a geometry‐defined quantum dot. In a perpendicular magnetic field, an Aharonov–Bohm flux breaks the m↔−m$m \leftrightarrow -m$ symmetry and yields a flux‐ and torsion‐tunable angular pseudospin (m=±1)$(m = \pm 1)$ with asymmetric ...

Correlated X‐Ray and Electron Microscopies of a Single Biphasic GaAs Nanowire

Small Methods, Volume 10, Issue 3, 9 February 2026.
Nano‐focused scanning X‐ray diffraction microscopy at a synchrotron light source, combined with transmission electron microscopy, reveals a clear correlation between the nanoscale distribution of cubic and hexagonal segments in a GaAs nanowire with subtle variations in inter‐reticular spacing, bending, and twisting.
