RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

Small, EarlyView.
Supramolecular helicity meets ferroelectricity: P3HT‐b‐PMMA helical nanowires enable handedness‐specific modulation of remanent polarization in P(VDF‐TrFE) hybrids. This platform demonstrates the first CPL‐addressable ferroelectric PUF, translating molecular chirality into secure digital authentication.

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 ...
