Scanning Tunneling Spectroscopy

SPIE Proceedings, 1988
Scanning 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, 2010
Abstract 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

Scanning tunneling spectroscopy studies of topological materials

Journal of Physics: Condensed Matter, 2020
Topological materials have become promising materials for next-generation devices by utilizing their exotic electronic states. Their exotic states caused by spin-orbital coupling usually locate on the surfaces or at the edges. Scanning tunneling spectroscopy (STS) is a powerful tool to reveal the local electronic structures of condensed matters ...

Channel selective scanning tunneling spectroscopy

Surface Science, 2006
Abstract In this paper we simulate STM and STS experiments for CO monomers and dimers on Cu(1 1 1) surface. We show that the contrast of STM images can be attributed to interference effects between tunneling channels, and suggest that functionalizing the microscope tip improves the channel selectivity of STM.

Scanning tunneling microscopy and spectroscopy

Uspekhi Fizicheskih Nauk, 1988
Scanning tunneling microscopy (STM) is a recent surface imaging technique discovered and put forward in 1982 by Binnig, Rohrer, Gerber and Weibel1. Their achievement was recognised in a short period of time by many prizes culminating in the Nobel Prize for Physics in 1986. Here we employ the acronym STM to denote either scanning tunneling microscopy or

Scanning Tunneling Spectroscopy

1993
Abstract By interrupting the feedback loop and keeping the tunneling gap constant and applying a voltage ramp on the tunneling junction, the tunneling current as a function of bias provides information that is the convolution of the tip DOS and the sample DOS. It is an extension of the tunneling junction experiment (Giaever, 1960, 1960a;

Scanning tunneling spectroscopy of Bi2Sr2CaCu2O8+

Physica C: Superconductivity, 1998
Abstract Cleaved surfaces of Bi 2 Sr 2 CaCu 2 O 8+ δ ( T c =86 K) have been investigated by low temperature scanning tunneling spectroscopy. The clean surface has been prepared by cleaving the sample at liquid helium temperature in a vacuum. The intrinsic superconducting density of states has been obtained in the tunneling spectra exhibiting a ...

Scanning Tunneling Spectroscopy

2005
Scanning tunneling spectroscopy (STS) and its extension, the spin-polarized scanning tunneling spectroscopy (SPSTS), reveal basic information on the spatial distribution of electron systems. STS measures the local density of states given by the sum over squared single-particle wave functions at a chosen energy, while SPSTS detects the spatial ...
