Simulating Scanning Tunneling Microscope

Imaging scanning tunneling microscope-induced electroluminescence in plasmonic corrals

An approach to image localized and propagating surface plasmon ~SP! modes is introduced. It is shown that scanning tunneling microscope ~STM!-electroluminescence, the radiative decay of SPs induced by inelastically tunneling electrons, observed in Fourier space yields distinct features that reflect the degree of delocalization and spatial distribution of SP modes. The propagating SP is isolated...

Scanning tunneling luminescence of individual CdSe nanowires.

The local luminescence properties of individual CdSe nanowires composed of segments of zinc blende and wurtzite crystal structures are investigated by low-temperature scanning tunneling luminescence spectroscopy. Light emission from the wires is achieved by the direct injection of holes and electrons, without the need for coupling to tip-induced plasmons in the underlying metal substrate. The p...

Morphological evolution of epitaxial cobalt–semiconductor compound layers during growth in a scanning tunneling microscope

We investigate the mechanisms of CoSi2 and CoGe2 growth by carefully controlled e-beam evaporation of Co onto Si~001! and Ge/Si~001! substrates from the very initial submonolayer stage, monitored in situ by scanning tunneling microscopy, aided by reflection high-energy electron diffraction. In order to grow different epilayer morphologies, we use flat and vicinal surfaces and two different meth...
