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...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
