| 摘要: |
| 为使单电子晶体管达到实际应用的地步，开展室温条件下相关研究成为必然。从正统理论出发，推导、计算出室温条件下单电子晶体管能否正常工作的库仑岛临界尺寸：存储器件为6.5nm，逻辑器件为1.5nm；本文还推导和计算出单电子晶体管室温下发生能量量子化效应的临界尺寸：4.7nm，并对这3种临界尺寸进行了验证和分析。另外，通过比较分析本文还得出了室温条件下，所有逻辑器件均必须考虑能量量子化效应，所有存储器件应尽量考虑能量量子化效应的结论。分析结果表明，库仑岛临界尺寸的确定对单电子晶体管的实际应用具有重要意义。 |

| Abstract: |
| To improve the capability of the single-electron transistor (SET) for the practical application, it is inevitable to make the researches under the condition of room temperature. Initialized from the orthodox theory, this research calculated the critical size of coulomb island of SET which can work normally at room temperature: the memory device is 6.5nm, the logic device is 1.5nm; it also calculated the critical size of coulomb island of SET when the energy quantization effect at room temperature, 4.7nm, appeared. Furthermore, it verified and analyzed these two kinds of critical size. In addition, through a comparative analysis, it drew conclusion that all logical devices must consider the energy quantization effect and all memory devices should consider the energy quantization effect at room temperature. The analysis result shows that determination for critical size of coulomb island has important significance for the application of SET. |
