The optical transmission spectrums for ZnSe thin films have been obtained in the spectral domain of 330 – 1400
nm. With the growth of the film thickness we observe a growth in the number of interference maxims and minims, and
for the thickness of d > 0.77μm, the difference between maximal and minimal transmission decreases. The presence of interference maxims and minims in transmission spectrums is determined by the multiple reflections from the film surface and represents an index that the samples are uniform and that film surfaces are plane. For thin layers with thickness d < 0.60 μm heat treatment leads to an increase in maximum and minimum interference, while for phase with the thickness d > 0.60 μm thermal treatment practically does not change the shape of the transmission spectrum. |
