Inhibition of Phase Segregation in Cesium Lead Mixed-Halide Perovskites by B-Site Doping

iScience, 2020
Summary: The emergence of all-inorganic halide perovskites has shown great potential in photovoltaic and optoelectronic devices. However, the photo-induced phase segregation in lead mixed-halide perovskites has severely limited their application. Herein,

Spin Noise of a Halide Perovskite

Physical Review Letters
We report on first observation of spin noise in a strongly birefringent semiconductor -- halide perovskite single crystal MAPbI$_3$. The observed spin noise resonance is ascribed to free holes with a record spin dephasing time of 4 ns. The spin dynamics is found to be affected by the residual light absorption of the crystal providing renormalization of
