Theory of a scanning tunneling microscope with a two-protrusion tip.
We consider a scanning tunneling microscope (STM) such that tunneling occurs through two atomically sharp protrusions on its tip. When the two protrusions are separated by at least several atomic spacings, the differential conductance of this STM depends on the electronic transport in the sample between the protrusions. Such two-protrusion tips commonly occur during STM tip preparation. We expl...
متن کاملTheory of the scanning tunneling microscope.
We present a theory for tunneling between a real surface and a model probe tip, applicable to the recently developed "scanning tunneling microscope." The tunneling current is found to be proportional to the local density of states of the surface, at the position of the tip. The effective lateral resolution is related to the tip radius R and the vacuum gap distance d approximately as [(2 A)(R +d...
متن کاملVariable-temperature independently driven four-tip scanning tunneling microscope.
The authors have developed an ultrahigh vacuum (UHV) variable-temperature four-tip scanning tunneling microscope (STM), operating from room temperature down to 7 K, combined with a scanning electron microscope (SEM). Four STM tips are mechanically and electrically independent and capable of positioning in arbitrary configurations in nanometer precision. An integrated controller system for both ...
متن کاملAtomic tunneling from a scanning-tunneling or atomic-force microscope tip: dissipative quantum effects from phonons.
We study the effects of phonons on the tunneling of an atom between two surfaces. In contrast to an atom tunneling in the bulk, the phonons couple very strongly and qualitatively change the tunneling behavior. This is the first example of Ohmic coupling from phonons for a two-state system. We propose an experiment in which an atom tunnels from the tip of an scanning-tunneling microscope, and sh...
متن کاملInvited Review Engineering of single molecules with a scanning tunneling microscope tip
The rapid progress in molecular manipulation with a scanning tunneling microscope (STM) tip opens up entirely new opportunities in nanoscience and technology. With these advances, the ultimate chemical reaction steps such as dissociation, diffusion, adsorption, re-adsorption and bond formation processes become possible to be performed by using the STM tip at the single molecule level with an at...
