How do I explain two broad peaks observed in Z'' vs log(frequency) with respect to relaxation mechanisms in an organic polycrystalline semiconductor?

I have also observed two semicircles in Nyquist plots. How do I relate this with Z'' vs log(frequency)? What might be the origin for these two semicircles in this type of material? How is this...

How do we identify the xrd peaks of (001), (100) and (010), where planes have the same d-spacing and hence the same 2theta?

If the 2theta value is the same for some planes, how do we identify them?

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
