Detection of surface plasmons by scanning tunneling microscopy

Scanning Tunneling Microscopy of Surface Structures

Surface science got a new impact with the development of the seanning tunneling microscope, since for the first time atomic-resolution observations of surface structures in real space have becomepossible. Following ashort description of the basic features of the seanning tunneling microscopy, some selected results are presented which illustrate the potential of the technique to provide informat...

Dynamic probe of ZnTe(110) surface by scanning tunneling microscopy

The reconstructed surface structure of the II-VI semiconductor ZnTe (110), which is a promising material in the research field of semiconductor spintronics, was studied by scanning tunneling microscopy/spectroscopy (STM/STS). First, the surface states formed by reconstruction by the charge transfer of dangling bond electrons from cationic Zn to anionic Te atoms, which are similar to those of IV...

Focusing and scanning microscopy with propagating surface plasmons.

Here we demonstrate a novel surface plasmon polariton (SPP) microscope which is capable of imaging below the optical diffraction limit. A plasmonic lens, generated through phase-structured illumination, focuses SPPs down to their diffraction limit and scans the focus with steps as small as 10 nm. This plasmonic lens is implemented on a metallic nanostructure consisting of alternating hole array...
