the chiral organic cations should have benzene rings to induce strong lattice distortion. The chirality of the methylbenzylammonium (MBA) cation is successfully transferred to the inorganic sublattices, and circular dichroism (CD) signals
The unique topology and physics of chiral superlattices make their self-assembly from nanoparticles highly sought after yet challenging in regard to (meta)materials1,2,3. Here we show that tetrahedral gold nanoparticles can transform from a perovskite-like, low-density phase with corner-to-corner ...
Topological systems are inherently robust to disorder and continuous perturbations, resulting in dissipation-free edge transport of electrons in quantum solids, or reflectionless guiding of photons and phonons in classical wave systems characterized by topological invariants. Recently, a new class of topolog...
