Multimodal electron microscopy of halide perovskite interfacial dynamics - Nature

Halide perovskite LEDs suffer rapid operational degradation due to ion migration and interfacial electrochemical reactions, requiring atomic-scale in situ imaging to understand degradation mechanisms and improve device stability.

A large-scale coherent 4D imaging sensor - Nature

Silicon photonics-based LiDAR systems offer compact, cost-effective 3D imaging by integrating light sources, imaging elements, and control electronics on a single chip for autonomous systems and spatial mapping applications.

Limitations of probing field-induced response with STM

We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.
