| 中文摘要 | Electron transport through a single CdS nanocrystal with the size of 2 nm was investigated using scanning tunneling microscope (STM) at room temperature in air. The nanocrystal was prepared by the exposure of 11-mercaptoundecanoic acid self-assembled monolayer adsorbed bivalent metal ions on Au(1 1 1) substrate to an HAS atmosphere. STM was employed to image, to position an individual CdS nanoparticle, and finally to detect its current-voltage (I-V) characteristics. The results demonstrated clear Coulomb blockade and Coulomb staircase effects in the I-V curves. Furthermore, by varying the distance between STM tip and CdS nanoparticle, we also found the dependence of staircase width on the air gap in the local I-V characteristics, which can be well explained in terms of semi-classical double-barrier tunneling model.
