A large-scale coherent 4D imaging sensor - Nature

Across various fields, from spatial mapping for reconnaissance and construction to facial recognition, virtual and augmented reality and autonomous driving, accurate 3D representation of dynamically evolving environments is paramount for safe human-machine interaction. Therefore, substantial research efforts are directed towards developing a cost-effective, high-performance and scalable 3D imaging sensor comparable with a CMOS camera.

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.
