| Abstract: | Pure and impurity added (with NH4Cl, NH4NO3, NH4H2PO4, and (NH4)2SO4) KDP single crystals were grown by the gel method using silica gels. X-ray diffraction data were collected for powder samples
and used for the estimation of lattice variation and thermal parameters like Debye-Waller factor, mean-square amplitude of
vibration, Debye temperature and Debye frequency. The thermal parameters do not vary in a particular order with respect to
impurity concentration. The results obtained are reported and discussed. |
