For example in NiFe thin films, if the concentration of Ni is change by wt% 33,40,50,60 in Fe .. what are the possible factors that changes the surface morphology (topography) of the thin film for each concentration ? (is change in lattice parameter can change the surface topography?? )
Dear colleague Ali Hassan Kazmi,
Have a nice time and good day,
Peace be up on you.
The surface morphology affects by the structural properties of produced material. Grain-boundary (regular or irregular), and particle size (shape- uniform or non uniform) may affect the surface morphology. Of course when you change the concentration of Ni in NiFe, the structure will be affected. It depends on if the produced alloy is stochiometric or not? which also affect the lattice parameters and consequently the phase structure.
If the grain size is regular and the particle size is uniform you will have smooth surface morphology and If the grain size is irregular and the particle size is non uniform you will have rough surface morphology.
I wish this is useful and help you.
Yours

The change the concentration of Ni in Fe, the structure will be affected. also affect the lattice parameters. . Also if the grain size is regular and the particle size is uniform you will obtain smooth surface morphology while If the grain size is irregular and the particle size is non uniform you will obtain rough surface morphology.
.
Also, if the lattice parameter change, the structural properties changes and the structural properties are related to the surface morphology
The density allow us to volume which could be occupied by the interstitials sites in front of the solubility. The porosity signifie no matter
@Akila Derardja can you please explain it ??The density allow us to volume which could be occupied by the interstitials sites in front of the solubility. The porosity signifie no matter??
I don't get you point. ?
The density allow us to know or to calculate the volume of the interstitials sites, I mean the compacity. These sites could be occupied by another atomes. Porosity can be related to the site where there is no matter.
