摘要：

Light emission from the tunneling junction of a scanning tunneling microscope (STM) has been used to obtain the electrical characteristics of small three-dimensional gold islands deposited on flat MOS2 surfaces. It is shown that these nanocontacts behave as poor rectifying junctions whose properties are altered by leakage currents. These properties are similar to those generally observed on point contacts where a sharp STM tip is brought in contact with a semiconductor. (C) 2003 American Institute of Physics.
