2024 Seed: CryoEM finds complexity in structural evolution of active materials
The realization of hybrid chiral and non-reciprocal excitations necessitates the development of new atomically-precise chiral solid state crystals and the understanding of the fundamental optical/electronic states that arise from the resulting structures
- Developed the chemistry towards the synthesis of well-defined and sizeable helical inorganic crystals based on the InSeI model phase
- Stimulus-responsive optical states showed highly sensitive thermochromic behavior, (dEg/dT)max = 1.26 × 10−3 eV K−1
- Record electron-phonon coupling strength in the visible range
- Led to understanding of the materials design rules and discovery of novel helices suitable for material interfacing to access hybrid chiral/non-reciprocal excitations
