Why MgO (110) and (111) are not effected by heat treatment??

I Did some heat treatment with MgO substrates with (100), (110), (111). I observe significant changes on MgO (100) surface morphology (atomic steps), but other two substrate remain unchanged....

Why Pt can not be deposited on Si substrate for the application of electrocatalytic applications?

Mostly ceramic substrates (MgO, STO, LaAlO3 etc..) are used to deposit transition Metals (Pt,Ag,Au,Cu) for the electrochemical applications. Why Silicon Substrate can not be used for such...

Why XRD patterns are indicating that Pt (110) and (111) are formed on MgO substrate but AFM shows some inappropriate structures?

Pt films deposited on MgO (110) and (111) were grown , as a result no elongated features and traces on MgO (110) and (111) were observed . Instead it was seen that a disordered 3 dimensional...

By Increasing the substrate temperature (Rt to 600c) we observe increase in the Peak Area graph from XRD 2theta analysis, What does that mean?

The intensity of the Graph is increasing with respect to temperature. If i plot a graph with respect to Area of that peak and temperature I observe also increase in area. what does that mean? If...
