Scanning Tunneling Spectroscopy of C36
The local density of electronic states NsEd has been measured on C36 thin films using scanning tunneling spectroscopy (STS). A 0.8 eV energy gap and sharp features in NsEd with widths as small as 0.2 eV can be ascribed to the discrete molecular energy levels predicted for the C36 molecule, broadened by intermolecular interactions. However, a more complete agreement between the experimental resu...
متن کاملScanning tunneling spectroscopy of high-temperature superconductors
Tunneling spectroscopy has played a central role in the experimental verification of the microscopic theory of superconductivity in classical superconductors. Initial attempts to apply the same approach to high-temperature superconductors were hampered by various problems related to the complexity of these materials. The use of scanning tunneling microscopy and spectroscopy (STM and STS) on the...
متن کاملScanning tunneling spectroscopy of graphene on graphite.
We report low temperature high magnetic field scanning tunneling microscopy and spectroscopy of graphene flakes on graphite that exhibit the structural and electronic properties of graphene decoupled from the substrate. Pronounced peaks in the tunneling spectra develop with increasing field revealing a Landau level sequence that provides a direct way to identify graphene and to determine the de...
متن کاملScanning tunneling spectroscopy of single DNA molecules.
We briefly present the results of recent experiments of transverse scanning tunneling spectroscopy of homogeneous poly(dG)-poly(dC) DNA molecules and discuss them in the light of theoretical investigation. A semiempirical theoretical model is adopted to describe the transverse tunneling current across a DNA molecule placed between a metallic gold substrate and a metallic STM tip. We show that t...
متن کاملDoping Profih g by Scanning Tunneling Spectroscopy
Scanning tunneling microscopy/spectroscopy is a new technique in many fields of pure and applied sciences. With STM/STP, one can not only image the sample surface with atomic resolution, but Mso probe the electronic structure of the sample. In the semiconductor industry, this unique capability is becoming an important tool since one needs to know the actual distribution of impurities in the dev...
