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