Spin-Polarized Scanning Tunneling Spectroscopy

2005
Within recent years spin-polarized scanning tunneling spectroscopy (SP-STS) has developed into a mature tool for ultrahigh spatial resolution magnetic domain imaging. In this chapter, we will introduce the measurement principle of SP-STS and describe experimental procedures and requirements. We will discuss present data measured on different ferro- and

Scanning Tunneling Spectroscopy in an Ionic Liquid

Journal of the American Chemical Society, 2006
Molecular redox levels can be used to modulate tunneling currents through single or small numbers of molecules and induce molecular electronic device function. While most of these devices require cryogenic conditions, room temperature operation has been demonstrated by using electrochemical gating in aqueous environments.

The scanning tunneling microscopy and scanning tunneling spectroscopy of amorphous carbon

Semiconductors, 2000
The most important methods for studying the surface of amorphous diamond-like carbon are scanning tunneling microscopy and scanning tunneling spectroscopy. In this review, publications concerned with studying the topography and electronic properties of the surface of amorphous diamond-like carbon films using a tunneling microscope are considered ...

Scanning tunneling spectroscopy of amorphous carbon: Tunneling model

Technical Physics Letters, 1999
An analysis is made of a model of tunnel current flow through amorphous diamond-like carbon. It is shown that single-electron phenomena may occur in this medium which result in the appearance of specific features on the current-voltage characteristics of thin amorphous carbon films. The model is used to explain the tunnel spectra of diamond-like carbon

Theory of scanning tunneling spectroscopy

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1988
A new three-dimensional tunneling theory is introduced for interpreting scanning tunneling spectroscopy (STS) images. By expanding the asymptotic wave function of the acting atom in terms of complete sets of eigenfunctions in spherical coordinates and parabolic coordinates, a derivative rule is derived, which can be applied to interpret scanning ...

Scanning Tunneling Microscopy and Spectroscopy

1987
Scanning Tunneling Microscopy (S.T.M.) is a real–space surface imaging method with atomic or subatomic resolution in all three dimensions which has been developed by 6. BINNIG and H. ROHRER. Besides imaging the surface topography, it also provides useful information on its electronic properties as well as spectroscopic images.

Scanning Tunneling Microscopy/Spectroscopy of Nanostructures

physica status solidi (a), 2001
The development of low-temperature scanning tunneling microscopes (STM) operating under ultrahigh vacuum conditions has provided new opportunities for investigating locally the electronic and magnetic structure at surfaces. Three examples are chosen from our laboratory, which illustrate the power and the potential of this local approach.
