How do we calculate the atomic scattering factor (f) in case of electron diffraction (for example in TEM)?

When choosing an X-ray target, it is said that the energy of incident k-alpha lines should be lesser than the energy of k-alpha lines of the material being studied. Therefore, generally Cu is not used as a target material for iron based materials. But, I have seen many works where Co is used as target for iron based materials. But, for cobalt as well the energy of k-alpha is higher than Fe-k-alpha. Then how can Co radiation give a proper output?

What will happen if other elements are used for generating X ray radiation and please also tell the benefit of using K(alpha) radiation ?

I am doing impedance measurements on my materials and I want to analyze in particular the real component of complex conductivity as a function of frequency.

I am not sure, but is it valid to take the real impedance, Z'(ν), as the resistance at a given frequency and calculate σ'(ν) = d/(Z'(ν)*A), where d and A are the thickness and area of my sample?

Hello,

Kindly what are the recommended methods or techniques for removing XRD impurities and how can one ensure accurate and reliable results ?

Thanks.

If molar fraction, atomic radius and electro negativity values are known then how to calculate mixing enthalpy?

Please describe in context of metals.

I have searched to find out what type of semiconductor MgO is. However, I couldn't find reliable explain.

I will be happy if you share your knowledge.

Thank u.

I need to calculate VEC for the constituent metals for an alloy synthesis. Is there any formula or data sheet to get the data of VEC?
