摘要：

Tunneling spectroscopy of Au (100)-(5x20) and Fe on Au(100) surfaces has been studied. Using a well-defined tunneling tip, I-S, I—V, and V/I*dI/dV-V spectra were obtained. The results confirm that the characteristics of the spectra resemble those of previously reported semiconductors. From I-S relations, it was found that the tunneling barrier decreases abruptly when the tunneling gap is < 6 Å. © 1990, American Vacuum Society. All rights reserved.
