What would be the X-ray diffraction intensity of a ternary compound with one atom spatially fluctuating inside the octahedra?

If a ternary ABC2 compound with two sublattices, say BC4 and AC8, where B and C are at the center of tetrahedra and octahedra respectively, suppose if A atom is randomly fluctuating inside the AC8...

Is there any possible way to distinguish between ETT and TPQT from high pressure XRD, Raman and resistivity studies?

ARPES study is the direct evidence for the topological insulating state. However, some of the trivial insulators can be transformed into non-trivial topological insulators by alloying, applying...

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...
