WebBriefly, the mixture of perovskite nanocrystal and chiral molecule were treated by microwave heating at 100 ℃ for half an hour with continuous stir. The high mass ratio (6.8) of perovskite and chiral molecule resulted in a single peak CD spectra with a g factor about 1.5 × 10 −3 (measured at 247 nm) [45], as depicted in Fig. 5 (a). WebJan 28, 2024 · Chiral phonon serves as a fundamental element in realizing nontrivial quantum mechanical phenomena. When chiral symmetry breaks in a crystal, chiral phonons emerge and can couple to spins leading to phenomena such as phonon Hall effect, optically driven effective magnetic field, AC Stark effect, topologically induced viscosity …
