Excited‐State Pathway Switching via Reversible Structural Phase Transitions in Sb3+‐Doped Cadmium Halides

Angewandte Chemie, EarlyView.
Octahedral (DFPD)6CdCl8:10%Sb and tetrahedral (DFPD)2CdCl4·H2O:5%Sb exhibit distinct luminescence dictated by coordination geometry. Solvent‐induced reversible phase transformation enables dynamic switching between yellow and deep‐orange emission. Combined experimental and computational studies elucidate the luminescence mechanisms, and the reversible ...

Interlayer‐Sliding‐Enabled Multiferroicity and Giant Switchable Anomalous Hall Conductivity in RuO2Zn2F2 Bilayer

Advanced Science, EarlyView.
Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting

, 2012
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction.

Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites

Advanced Science, EarlyView.
This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...

Induced Gravitational Collapse in the BATSE era: the case of GRB 970828

, 2014
Following the recently established "Binary-driven HyperNova" (BdHN) paradigm, we here interpret GRB 970828 in terms of the four episodes typical of such a model. The "Episode 1", up to 40 s after the trigger time t_0, with a time varying thermal emission
