Electrical Tunability of Quantum-Dot-in-Perovskite Solids.

The quantum-dot-in-perovskite matrix (DIM) is an emerging class of semiconductors for optoelectronics enabled by their complementary charge transport properties and stability improvements. However, a detailed understanding of the pure electrical properties in DIM is still in its early stage. Here, we developed PbS quantum dot-in-CsSnI matrix solids exhibiting improved electrical properties and enhanced stability.
