Pressure-induced structural transformation in potassium stanichloride
P Kistaiah K Sathyanarayana Murthy Leela Iyengar K V Krishna Rao
Pressure-induced structural transformation in potassium stanichloride has been studied by x-ray diffraction at room temperature. The change in the diffraction pattern started at about a pressure of 15 kbar and continued upto 50 kbar. The pattern recorded at about 50 kbar could be indexed basing on an orthorhombic lattice, with lattice parameters

X-ray studies on the thermal expansion of copper indium disulphide
P Kistaiah Y C Venudhar K Sathyanarayana Murthy Leela Iyengar K V Krishna Rao
The lattice parameters of the compound copper indium disulphide (CuInS2) have been measured by x-ray diffraction. The data have been used to evaluate the coefficients of thermal expansion, perpendicular and parallel to the principal axis. The thermal expansion studies revealed the anisotropy between the axial expansion coefficients having a larger coefficient of expansion along

Lattice thermal expansion of silver indium disulphide
P Kistaiah K Satyanarayana Murthy K V Krishna Rao
Lattice parameters of chalcopyrite type compound silver indium disulphide (AgInS2) were determined as a function of temperature by the x-ray method in the temperature range 28 to 685°C. Using these data, the coefficients of thermal expansion,
