Atomic Structure of Grain Boundaries, Dislocations and Associated Strain in Templated Co-evaporated Photoactive Halide Perovskites
Huyen T Pham, Siyu Yan, Zhou Xu +4
Structural defects, particularly grain boundaries, play a crucial role in governing charge transport and the optoelectronic properties of metal halide perovskites, thereby limiting…
Discovery of Ferroelectric Twin Boundaries in a Photoactive Halide Perovskite
Weilun Li, Qimu Yuan, Michael B. Johnston +1
Halide perovskites have emerged as promising materials for next-generation photovoltaics, laser sources and X-ray detectors. There is intense debate as to whether some photoactive…
Locating the Atoms at the Hard-soft Interface of Gold Nanoparticles
Weilun Li, Bryan D. Esser, Wenming Tong +7
Surface structure affects the growth, shape and properties of nanoparticles. In wet chemical syntheses, metal additives and surfactants are used to modify surfaces and guide nanocr…
Ruddlesden-Popper defects act as a free surface: role in formation and photophysical properties of CsPbI3
Weilun Li, Qimu Yuan, Yinan Chen +5
The perovskite semiconductor, CsPbI3, holds excellent promise for solar cell applications due to its suitable bandgap. However, achieving phase-stable CsPbI3 solar cells with high…
