Frustrate microstructures composed PbS cluster’s size perspective from XRD by variant models of Williamson-Hall plot method

Abstract The coherent crystalline domain Size of a particle is well understood and investigable from the broadening of XRD peaks by Williamson-Hall (WH) method in connection with a strain, and it has a close correlation with the strain, stress, energy density, defects/dislocations. The coherent domain size of binary semiconducting material particles is being interlinked with the applications like sensors, solar systems, photo-detectors, photocatalyst etc. In the present work, the frustrated cluster of PbS elucidated the perspective of different models of the WH method. Frustrated microstructural PbScluster was prepared, confirmed and rendered its microstructural analysis from the XRD data and SEM. Eight various approaches as the variant models of the Williamson Hall plotting methods have been tested. It includes the models like Balzar approach, UDM, UDSM, UDEDM, modified WH model, Ehkl/E0ratio model, Direct fitting of simplified WH model with introducing new approach and the modified Kibasomba-WH model which uses linearization of Scherrer equation with the WH method. Present work lightens the USDM and UDEDM sizes in an account of a Zener constant. The other non-WH methods like the Scherrer formula method, modified Scherrer method, Stress-Strain methods and Halder-Wagner method are also included for comparison and to see their status in a cluster of frustrated structures. The sizes in connection with strain, stress, energy density, dislocation and stacking fault, have been also investigated for the frustrated PbS cluster.
