室温工作的单电子晶体管研究

Research of Single Electron Transistors Operated in Room-temperature

由于具有低功耗、高速度、高集成度等优点,单电子晶体管成为最有前景的纳米电子功能器件之一。但是,由于结构上的特殊性,单电子晶体管只能在低温下正常工作,该特性限制了其实用化进程。因此,研究可在室温下工作的单电子晶体管具有重要意义。在分析单电子晶体管工作机理的基础上,计算了单电子晶体管室温工作的基本条件,并实验制备出了样片。测试结果表明,所制备的单电子晶体管可在室温下表现出库仑振荡等基本特性。该研究成果将为单电子晶体管的集成实用化打下良好的基础。

The single electron transistor （SET） has become one of the most promising components in nanometer electronic functional devices because of its advantages of low power consumption, high speed and high integration. But due to the special features in structure, SET usually operates only in very low temperature, which prevents SET from being feasible devices. Therefore, it is very important to investigate SET which operates in room-temperature. In this paper, based on the analysis of working mechanism of SET, we calc^ate the conditions in which SET can operate in room-temperature, then prepare SET samples in laboratory. The measurement results show that the prepared SET can operate normally in room-temperatmre. The research findings will deliver a fine foundation for the practical application of SET.
