Structural and optical studies of local disorder sensitivity in natural organic–inorganic self-assembled semiconductors
Structural and optical studies of local disorder sensitivity in natural organic–inorganic self-assembled semiconductors
The structural and optical spectra of two related lead iodide (PbI) based self-assembled hybrid organic–inorganic semiconductors are compared. During the synthesis, depending on the bridging of organic moiety intercalated between the PbI two-dimensional planes, different crystal structures are produced. These entirely different networks show different structural and optical features, including excitonic bandgaps. In particular, the modified organic environment of the excitons is sensitive to the local disorder both in single crystal and thin film forms. Such information is vital for incorporating these semiconductors into photonic device architectures.

Abstract
The structural and optical spectra of two related lead iodide (PbI) based self-assembled hybrid organic–inorganic semiconductors are compared. During the synthesis, depending on the bridging of organic moiety intercalated between the PbI two-dimensional planes, different crystal structures are produced. These entirely different networks show different structural and optical features, including excitonic bandgaps. In particular, the modified organic environment of the excitons is sensitive to the local disorder both in single crystal and thin film forms. Such information is vital for incorporating these semiconductors into photonic device architectures.
