英文摘要：

The periodical characteristics of double-island single-electron transistor （SET） were analyzed by stable diagram and Monte-Carlo method. Seven typical states were selected to simplify the master-equation simulation, and to improve the limitation of the method by the periodical characteristics. The result shows that the proposed method can efficiently simulate the current and voltage character of double-island SET, and can be simply extended to multi-island SETs, which is very useful for the VLSI of multi-island SETs.
