Abstract

CdSo~Seo.6 nanocrystals have been formed through nucleation and growth processes during heat treatments at different temperatures (T = 600, 675 and 700°C) and annealing times (t = 1 hour to 8 days). A regime of nucleation and growth seems to occur at T = 600OC. The growth process is dominant at T = 675 and 700°C. The average size of the semiconductor… (More)
