Design Rules for Quantitative Control of Intragrain Planar Defects in Halide Perovskites. [PDF]

Adv Sci (Weinh)
Dose‐budgeted electron microscopy reveals the design rules governing intragrain planar defects in halide perovskites: {112}t ferroelastic twins proliferate with increasing tetragonality and grain size, whereas {111}c twins and stacking faults emerge as the lattice approaches cubic symmetry.

Static Disorder in Lead Halide Perovskites

The Journal of Physical Chemistry Letters, 2022
In crystalline and amorphous semiconductors, the temperature-dependent Urbach energy can be determined from the inverse slope of the logarithm of the absorption spectrum and reflects the static and dynamic energetic disorder. Using recent advances in the sensitivity of photocurrent spectroscopy methods, we elucidate the temperature-dependent Urbach ...

Defect Activity in Lead Halide Perovskites [PDF]

Advanced Materials, 2019
AbstractThe presence of various types of chemical interactions in metal‐halide perovskite semiconductors gives them a characteristic “soft” fluctuating structure, prone to a wide set of defects. Understanding of the nature of defects and their photochemistry is summarized, which leverages the cooperative action of density functional theory ...
