Autor: Yaroslav Boyko, Andriy Luchechko, I. B. Olenych, Liubomyr S. Monastyrskii, Andriy Kostruba

Publikováno v: Applied Nanoscience. 9:781-786

In this work the nc-Si/SiOx nanosystems were obtained on the silicon substrate by means of evaporation of silicon powder in an oxidizing atmosphere. Then deposited SiOx films were irradiated from 226Ra isotope and were annealed at 1000 °C to grow nc
