Why XRD patterns are indicating that Pt (110) and (111) are formed on MgO substrate but AFM shows some inappropriate structures?

Pt films deposited on MgO (110) and (111) were grown , as a result no elongated features and traces on MgO (110) and (111) were observed . Instead it was seen that a disordered 3 dimensional...
