Scanning Tunneling Spectroscopy
Annual Review of Analytical Chemistry, 2009The scanning tunneling microscope (STM) has revolutionized our ability to explore and manipulate atomic-scale solid surfaces. In addition to its unparalleled spatial power, the STM can study dynamical processes, such as molecular conformational changes, by recording current traces as a function of time.

In this work, direct observation of ambipolar self-doping in hybrid lead-iodide perovskites has been reported through scanning tunneling spectroscopy (STS) and, thereby, density of states (DOS).

Theory of scanning tunneling spectroscopy
Vacuum, 1989Abstract Recent developments of the theory of Scanning Tunneling Spectroscopy (STS) are reviewed. The basis for the use of the Scanning Tunneling Microscope (STM) as a spectroscopic tool is first discussed. Then, we review the studies of the interface potential and its change as the gap width is varied; in this context, the calculations of the contact ...

Scanning Tunneling Vibrational Spectroscopy
Spectroscopy Letters, 1997Abstract A new method for studying of vibronic transitions by scanning tunneling microscope (“nitraresonator electron-vibronic scanning tunneling spectroscopy of adsorbates”) is proposed. Results of experiments carried out by STM “Omicron” where electron-vibronic series of field emission resonances were observed are presented.

Data scattering in scanning tunneling spectroscopy
Ultramicroscopy, 2008We investigated the scattering of current-voltage data obtained with scanning tunneling spectroscopy (STS) at room temperature at a solid-liquid interface on highly oriented pyrolytic graphite (HOPG) and in ultrahigh vacuum on HOPG and Au(111). For both experimental conditions, the data scattering can be described by a lognormal function for a moderate

Scanning Tunneling Spectroscopy
SPIE Proceedings, 1988Scanning tunneling microscopy (STM) provides a means of directly imaging surface topography with atomic scale resolution. Scanning tunneling spectroscopy (STS) usually refers to the image-wise determination of the tunnel current variation with bias voltage for fixed tunnel gap width.

Scanning tunneling spectroscopy on Bi2SrCaCuO6+
Physica C: Superconductivity and its Applications, 2010Abstract Scanning tunneling microscopy and scanning tunneling spectroscopy (STS) measurements were performed on Bi2SrCaCuO6 whose superconducting transition temperature Tc is about 80 K. The superconducting gap obtained by the STS measurements was found to be about 40 meV. This value is close to that of optimally doped Bi2Sr2CaCu2O8 which has similar
