Chirality Unlocks Sub-Terahertz Molecular Dynamics In Peptide Nanotubes.

Low-frequency modes in the picosecond range play a key role in molecular recognition and biomolecular function. Here, we investigate how these dynamics at the interfaces of self-assembled peptide biomaterials relate to fine structural details of the supramolecular assembly. We resolve terahertz and mid-infrared modes i...

Mixed Triple-Cation Tin and Lead Bromide Perovskites: Bridging Atomic Structure, Lattice Dynamics, and Stability

Tin-based halide perovskites are promising lead-free alternatives for optoelectronic applications, yet their practical implementation is limited by the facile oxidation of Sn(II) to Sn(IV), which compromises environmental stability. Inspired by the success of triple-cation engineering in Pb-based perovskites, we expl...
