FE-SEM images of all the samples. For all the samples, the columnar shaped ZnO grains grown normal to the substrate surface are clearly seen. When MZO and GZO films are deposited after ZnO films, it seems that similar columnar shaped grains are formed. It can indicate if the same conditions are preserved, all films can be grownvertically. It is very similar patterns reported in literature [1].
optical microscopes can be very simple, although there are many complex designs which aim to improve resolution and sample contrast.

1) Bright-field microscopy
Bright-field microscopy is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted white light and contrast in the sample is caused by absorbance of

The laser beam traces a cross-section of the part pattern on the surface.
Exposure to the ultraviolet laser light cures and solidifies the pattern.
