After formation of a thin film, should the urbach energy value be always less than that of bandgap energy?

if the values of urbach energies come greater than the values of bandgap energy, what does this bear significance?

May I get assisted with some articles which refers to two separate metals like Mg and Cu doped ZnO thin film for its characterization methods?

Actually I can not find any suitable articles which can clarify about the compare and contrast technique of any parameters I obtain, like the bandgap. How can I write in quality; the compare and...
