摘要
用简谐势描述量子点中电子所受的约束 ,通过简谐势模型利用自洽迭代的方法计算了Cd S、Pb S等半导体纳米粒子的充电电容 ,从而找到了其在室温下形成单电子器件的最大粒径 .
With the harmonic potentials, the binding of electrons in the dots is described. The capacitance of semiconductor nanoparticles CdS,PbS are computed by harmonic potentials Model with self-consistent method.The maximum quantum do t size is also found,which can form the Single Electron Transistor in room temper ature.
