Imaging Anyons with Scanning Tunneling Microscopy

Imaging Anyons with Scanning Tunneling Microscopy

Anyons are exotic quasiparticles with fractional charge that can emerge as fundamental excitations of strongly interacting topological quantum phases of matter. Unlike ordinary fermions and bosons, they may obey non-Abelian statistics—a property that would help realize fault-tolerant quantum computation. NonAbelian anyons have long been predicted to occur in the fractional quantum Hall (FQH) ph...

Imaging ultrathin Al2O3 ®lms with scanning tunneling microscopy

Reproducible scanning tunneling microscopic (STM) images were obtained from ultrathin Al2O3 ®lms epitaxially grown on Re…0001†. Initially, the oxide ®lms grow two-dimensionally in a layer-by-layer fashion with well-ordered surface morphologies. As the oxide ®lm thickens to ca. 9 monolayer equivalents (MLE), the surface roughens and becomes more disordered yet still exhibits signi®cant long-rang...

Scanning Tunneling Microscopy

The invention of the scanning tunneling microscope was a singularity event in the field of surface science and condensed matter physics. The ability to visualize individual atoms in an atomic structure was a huge step forward in experimental development, one for which the inventors were awarded the Nobel Prize in Physics in 1986. While a groundbreaking development, the Scanning Tunneling Micros...
