Abstract

It is very interesting that magic electron affection promotes growth of nanocrystals due to nanoscale characteristics of electronic de Broglie wave which produces resonance to transfer energy to atoms. In our experiment, it was observed that silicon nanocrystals rapidly grow with irradiation of electron beam on amorphous silicon film prepared by pulsed laser deposition (PLD), and silicon nanocrystals almost occur in sphere shape on smaller nanocrystals with less irradiation time of electron beam. In the process, it was investigated that condensed structures of silicon nanocrystals are changed with different impurity atoms in silicon film, in which localized states emission was observed. Through electron beam irradiation for 15 min on amorphous Si film doped with oxygen impurity atoms by PLD process, enhanced photoluminescence emission peaks are observed in visible light. And electroluminescence emission is manipulated into the optical communication window on the bigger Si-Yb-Er nanocrystals after irradiation of electron beam for 30 min.

摘要

非常有趣的是，由于电子德布罗意波的纳米尺度特性，其产生共振将能量传递给原子，神奇的电子效应促进了纳米晶体的生长。在我们的实验中，观察到在通过脉冲激光沉积（PLD）制备的非晶硅薄膜上用电子束辐照时，硅纳米晶体迅速生长，并且在电子束辐照时间较短的较小纳米晶体上，硅纳米晶体几乎呈球形出现。在此过程中，研究了硅纳米晶体的凝聚结构如何随硅薄膜中不同杂质原子而变化，其中观察到了局域态发射。通过对采用PLD工艺掺杂氧杂质原子的非晶硅薄膜进行15分钟的电子束辐照，在可见光中观察到增强的光致发光发射峰。在对较大的Si-Yb-Er纳米晶体进行30分钟的电子束辐照后，电致发光发射被调控到光通信窗口。
