Is it possible to find out the in-plane lattice constant for a polycrystalline film without doing in-plane XRD and Reciprocal space mapping?

I am trying to calculate strain in GeSn system. From theta-2 theta XRD scan, the films turn out to be polycrystalline in nature showing three slightly shifted peaks (with different concentration...

How can I study the motion of defects in a semiconductor and their impact on the performance of associated device (e.g. a solar cell)?

Suppose the defects in a semiconductor are changing their position with time. How can I study their effect on the opto-electronic properties of the semiconductor and eventually, on the device? Is...
