In this work, we studied, at low temperature, the coherent evolution of the localized electron and hole spins in a polycrystalline film of CH3NH3PbI3 (MAPI) by using a picosecond-photo-induced Faraday rotation technique in an oblique magnetic field.

International audience; Micro-photoluminescence measurements have been performed on single cubic-shaped CsPbCl3 nanocrystals (NCs) with side lengths of nearly twice the Bohr diameter, i.e. in the intermediate confinement regime. We observed two peaks

International audience; We synthesized strongly anisotropic CsPbBr3 nanocrystals with very narrow emission and absorption lines associated to confinement effects along one or two dimensions, called respectively nanoplatelets (NPLs) and nanosticks (NS

Physical Review B, American Physical Society, 2020, 102 (16), ⟨10.1103/PhysRevB.102.165314⟩

We study the magnetic-field dependence of the longitudinal spin relaxation time ${T}_{1}$ of donor-bound electrons placed in the middle of an 8-nm CdTe quantum well with different doping concentrations in the range from $1\ifmmode\times\else\texttime
