Abstract

Controlling the formation, size distribution and orientation of quantum wells (QWs) in layered hybrid perovskite (LHP) thin films is foundational to their optoelectronic device applications. These applications require exquisite control of energy and charge transport which tend to be highly anisotropic in low-dimensional phases in LHP thin films. Here, we combine a powerful suite of multimodal in situ characterizations to elucidate the precise solution-to-solid conversion of the sol into the LHP thin film. We identify, for the first time, the presence of oriented colloidal transient nanostructures during spin coating well before the onset of crystallization of phases.
