Publikováno v: Science Advances. 8(30)

Monitoring of the spatially resolved exciton spin dynamics in two-dimensional semiconductors has revealed the formation of a spatial pattern and long-range transport of the spin-polarized excitons, which holds promise for exciton-based spin-optoelect

Metal-free ferroelectric halide perovskite exhibits visible photoluminescence correlated with local ferroelectricity

Autor: Taketo Handa, Ruito Hashimoto, Go Yumoto, Tomoya Nakamura, Atsushi Wakamiya, Yoshihiko Kanemitsu

Publikováno v: Science advances. 8(25)

Perovskite materials with tunable electronic and structural characteristics can realize various physical properties including electrical/ionic conduction, ferroelectricity, and luminescence. Integrating and coupling these properties in a single perov

The toxicity of lead perovskite hampers the commercialization of perovskite-based photovoltaics. While tin perovskite is a promising alternative, the facile oxidation of tin(II) to tin(IV) causes a high density of defects, resulting in lower solar ce
