  • Phase singularities are intimately related to orbital angular momentum. Direct local imaging of orbital angular momentum effects at the nanoscale remains challenging. Here, the authors demonstrate via scanning tunnelling microscopy that inter-orbital angular momentum scatterings induced by asymmetric potentials can modulate the phase singularities and induce single-wavefront dislocations.

  • Orbital hybridization in artificial atoms is achieved by altering their shape, and the anisotropy of the confining potential gives rise to the hybridization between quasibound states with different orbital quantum numbers within the artificial atom.

  • Layers of transition metal dichalcogenides (TMDs) are generally formed by covalently bonded atoms, enabling mechanical exfoliation only in the out-of-plane direction. Here, the authors show the fabrication of fractional 2/3-layers of WTe2 and other TMDs by applying local scanning tunneling microscopy tip pulses and controllably removing the topmost chalcogen atoms.
