Molecularly Engineered Organic-Inorganic Hybrid Perovskites Quantum Wells
- Summary
- Researchers at Purdue University have developed a molecular approach to the synthesis of high quality organic/inorganic hybrid perovskite quantum wells with tunable structures and band alignments. The new solution-processed semiconductor quantum wells help those who want to build efficient, low-cost, flexible light emitting diodes, lasers, photodetectors, transistors, and solar cells by combining organic/inorganic semiconductors into well-defined nanostructures.This technology allows the strong self-aggregation of the conjugated organic molecules to be suppressed, and 2D organic-halide perovskite superlattice crystals and thin films to be easily obtained via one-step solution processing.

None
- *Background
- Two-dimensional (2D) semiconductor superlattices (or quantum wells) are key building blocks in modern optoelectronics. The ability to simultaneously realize defect-free epitaxial growth and to individually fine-tune the chemical composition, layer thickness, and band structure of each layer is essential for achieving the desired device performance. Such structures are challenging to fabricate using organic or hybrid materials. There is a need for method to realize these structures more efficiently and cost effectively.
