Multiquantum vortices in superconductors: Electronic and scanning tunneling microscopy spectra

Superconducting quasiparticle excitation spectra are computed for m times quantized flux lines using a self-consistent Bogoliubov–de Gennes approach. We find m discrete branches of bound-state solutions in the spectrum, corresponding to different values of the quasiparticle angular momentum. Owing to the bound states, the scanning tunneling microscopy spectrum of the vortex is predicted to disp...

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...

Scanning tunneling microscopy

This paper begins with a brief introduction the development of scanning tunneling microscopy (STM); in the second part, we will present some basic theory about STM, we will pay more attention on the theory for tunneling between the surfaces of the sample with the model probe tip. Next, we introduce the STM facility, include different modes of operation and other influence factors. In addition, ...
