摘要
介绍了非对称性势垒单电子管(ATBs)的电路模拟和特性,以及采用准经典的Monte Carlo方法对Ge/Si复合纳米结构MOSFET存储器的电路模拟,得出由于台阶状复合势垒的作用,在擦写时间保持μs和ms量级的同时,存储时间可长达数年.从而解决了快速编程与长久存储之间的矛盾.
In this paper,the property and circuit simulation of the Single Electron Device based on Asymmetric Tunnel Barriers, and the Ge/Si nanocrystal MOSFET memory with the Monte Carlo method in quasic classical approximation are introduced. It is demonstrated that the proposed device can achieve the programming in the order of/~s or ms owing to the hetero-energy bands, and the retention time is increased to several years at the same time. Hence the conflict between high speed programming and long retention can be efficiently resolved.
