Physique

About carrier's self-trapping and dynamical Rashba splitting in the two-dimensional hybrid perovskite (BA) 2 (MA) 2 Pb 3 I 10

Time-and Angle-Resolved Photoelectron Spectroscopy is employed to monitor photoexcited electrons in the two-dimensional (BA)2(MA)2Pb3I10. ARPES intensity maps are in good agreement with ab-initio calculations of the band structure. The effective…

Anomalous high-density spin noise in a strongly interacting atomic vapor

Spin noise spectroscopy (SNS) has become a mainstream approach to probe the dynamics of a spin ensemble in and out of equilibrium. Current models describing spin noise in interacting samples are based on an effective single-particle dynamics in a…

Vapor Deposition of Hybrid Halide Perovskites in Ultra-High Vacuum: Challenges Revealed by Probing the Organization Dynamics in Real Time

With record efficiencies and reduced costs, hybrid halide perovskite solar cells could revolutionize photovoltaics, provided that the crippling instability problem is resolved. To reveal the relationship between structural defects and instability,…

Photodynamic Therapy Using Pulsed-Laser Irradiation of Gold Nanoparticles for the Treatment of Cancers with High Basal Oxidative Stress

For over 20 years, considerable research has been carried out on the use of nanotechnologies in cancer treatment. Beyond the photothermal effect of irradiating gold nanoparticles, the photodynamic effect with reactive oxygen species (ROS) production…
