Designing chiral organic small molecules for circularly polarized light detection via group theory

InfoMat, Volume 8, Issue 8, August 2026.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Variations in Stochastic Magnetic Tunnel Junctions

physica status solidi (a), Volume 223, Issue 14, 22 July 2026.
This work presents a reproducible fabrication method for nanoscale stochastic magnetic tunnel junctions (s‐MTJs) using undercut‐assisted e‐beam lithography, end‐point‐controlled etching, and in situ passivation. The study identifies key variation sources, such as static characteristic variations in TMR, resistance, coercive field, and loop shift ...
