Visualizing perovskites’ energetic (nano)landscape

This artistic representation shows charge carriers in alloyed halide perovskites funnelled into local hotspots to emit light. The mechanism shows defect tolerance and can be beneficial for solar cell applications.

  • In moiré superlattice van der Waals magnetic materials, competing interactions emerge and can stabilize new magnetic states. Here, stacking-dependent interlayer exchange interactions in small-twist-angle CrI3 bilayers yield an ordered ground state with coexisting ferromagnetic and antiferromagnetic regions.

  • Quantum fluctuation in a vacuum can induce a measurable force between neutral objects in close vicinity. By dynamically modulating a system of two micromechanical oscillators near an exceptional point in the parameter space, this so-called Casimir effect can induce a non-reciprocal, diode-like energy transfer.

  • An artificial molecular machine was designed by coupling a chemical equilibrium to a photoresponsive molecular motor. Upon light illumination, the rotary movement of the motor performs work on the chemical equilibrium generating a far-from-equilibrium state.
