What to know about Careful crystallization unlocks well-ordered perovskite layers for transistors

Researchers led by Tomasz Marszalek have developed a solvent vapor-assisted drop-casting method to improve the crystallization of Dion-Jacobson perovskite layers. This approach allows for better molecular organization, which enhances the electrical properties of the materials for use in high-performance transistors.
