- Abstract
- A periodic nano-island array of similar to 7 nm diameter Zn single crystals embedded in an amorphous Zn2xSi1-xO2 layer was created by using rapid electron beam irradiation for 50 s. A sequential process of 900 degrees C thermal annealing followed by electron beam irradiation induces the formation of an amorphous Zn2xSi1-xO2 layer containing periodic Zn nanocrystals. It is shown that the periodic Zn crystal array can be produced with good control of their size and spacing. Possible formation mechanisms for the Zn crystal nano-islands are described on the basis of the experimental results.
