Cold‐Sublimating Quasi‐Solid Additive Enables High Efficiency and Long Operational Stability Binary Organic Solar Cells

open access: yesAdvanced Energy Materials, Volume 16, Issue 5, 4 February 2026.
Cold‐sublimating quasi‐solid mDF acts as an in situ‐removable transient structuring agent that broadens solvent‐removal, accelerates intermediate crystallization, and tightens π–π stacking in PM6:L8‐BO OSCs. Offering residue‐free morphology control, mDF‐treated OSCs enable high efficiency and a markedly extended operational lifetime (T80 = 477 h ...

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

open access: yesAnnalen 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 ...

Compact Terahertz Dual‐Comb Spectroscopy with All‐Digitally Generated Adaptive Clock

open access: yesAdvanced Physics Research, Volume 5, Issue 2, February 2026.
This work demonstrates a compact terahertz dual‐comb spectrometer using an all‐digital adaptive clock generated on an FPGA. This system achieves high precision across 1.6 THz, resolves over 24 000 comb lines with kHz resolution, and offers enhanced stability and a simplified architecture compared to analog‐based methods.

High‐Sensitivity, High‐Resolution Stimulated Raman Photoacoustic Spectroscopy Enabled by Continuous‐Wave Intracavity Pump‐Stokes Beams

open access: yesLaser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.
High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...
