Abstract

The influence of the growth rate of CdS, CdSe and CdTe films on their polycrystallinity is discussed in this report. CdS, CdSe and CdTe films were fabricated by chemical vapor deposition in hydrogen flow. The growth rate of films was varied in sufficiently wide range of 10 104 A/sec. Samples had polycrystalline or amorphous structures depending on the growth rate. Minimal critical temperatures (Tc) at which polycrystalline films were deposited have been established. Films had amorphous structures at temperatures deposited below Tc and polycrystalline structures deposited at temperatures more than Tc. The growth rate of the polycrystalline films was increased with the deposition temperature. The increasing of the growth rate or the decreasing of the deposition temperature led to amorphous structure. For polycrystalline films the grain sizes were decreased with the growth rate at the same deposition temperatures. Results obtained are explained by the critical flux of evaporating and condensing molecules.
