Abstract
Self-assembling conditions for 1O4Ca tetrahedral nanoclusters in ZnTe:(Ca, O) with Ca content up to 0.02 and with the ultradilute limit of oxygen are represented. The causes of self-assembling are a CaO and ZnTe bonding preferential over a CaTe and ZnO one and decrease of the strain energy after nanocluster formation. Self-assembling conditions were studied in the temperature range from 200 ∘C to 1305 ∘C. The occurrence of nanoclusters depends only on the Ca content and temperature. The temperature of self-assembling completion when all oxygen atoms are in 1O4Ca nanoclusters is determined by the Ca and oxygen contents.
