  • Li et al. report large circular dichroism in 2D chiral perovskite single crystals, arises from the inorganic sublattice, instead of chiral ligands, driven by electron-hole exchange interactions. This is evidenced by both reflective circular dichroism spectroscopy and ab initio theory.

  • Two-dimensional hybrid perovskites have gained substantial interest recently due to their controllable optoelectronic properties; however precise control over layer thickness has been synthetically challenging. Now a crystal growth method is shown to achieve high-quality single crystals of organic semiconductor-incorporated perovskites with control over their thickness and length through judicious solvent choice, affording precisely tuned optoelectronic properties.

  • The layer stacking order in 2D materials can be used to control functional properties. Here, the authors find a thickness effect, where thin flakes of MoTe2 display stacking arrangements different from bulk crystals.
