Scanning Tunneling Spectroscopy of C36
نویسندگان
چکیده
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 results and theoretical predictions occurs if the system is modeled as covalently bonded C36 dimers and trimers. These results confirm the molecular nature of C36 as well as its higher reactivity as compared to larger size fullerenes. [S0031-9007(98)08156-3]

Infrared spectroscopy of molecular submonolayers on surfaces by infrared scanning tunneling microscopy: tetramantane on Au111.
We have developed a new scanning-tunneling-microscopy-based spectroscopy technique to characterize infrared (IR) absorption of submonolayers of molecules on conducting crystals. The technique employs a scanning tunneling microscope as a precise detector to measure the expansion of a molecule-decorated crystal that is irradiated by IR light from a tunable laser source. Using this technique, we o...
متن کاملVacuum tunneling of superconducting quasiparticles from atomically sharp scanning tunneling microscope tips
We report on the study of atomically sharp superconducting tips for scanning tunneling microscopy and spectroscopy. The results clearly show vacuum tunneling of superconducting quasiparticles from atomically sharp tips. Observed deviations of the energy gap of the superconducting tip from its bulk value are attributed to the proximity effect. We show that a combination of a superconducting tip ...

Characterization of tungsten tips for STM by SEM/AES/XPS
For the first time, both X-ray Photoelectron Spectroscopy (XPS) and Auger Electron Spectroscopy (AES) techniques were applied in analysis of surface contamination of electrochemically etched Scanning Tunneling Microscope (STM) tungsten tips. Carbon monoxide, graphite, tungsten carbide and tungsten oxide were found as main surface contaminations of STM tungsten tips. The thickness of tungsten ox...
متن کاملAsymmetry of electron transmission through monolayers of helical polyalanine adsorbed on gold surfaces.
Polyalanine derivatives containing cysteamine linker R-(Ala)14NH-(CH2)2-SH, where R is ferrocenecarbonyl or hydrogen, were synthesized and then used to form self-assembled monolayers on gold. The tilt angles and the packing density of the molecules within monolayer assemblies were determined by FTIR spectroscopy and scanning tunneling microscopy, respectively. Electrochemical properties of mono...
