Investigation of diffraction line broadening due to compositional fluctuations in l-alanine-doped triglycine sulfate

Broadening of X‐ray powder diffraction peaks as a result of compositional disorder in l‐alanine‐doped triglycine sulfate crystals is investigated using the Williamson–Hall method. The analysis indicates that l‐alanine substitution in triglycine sulfate crystals leads to anisotropic strain in the cry...
