A possible growth mechanism is proposed using the results of these studies. The texture coefficient values of all the structures, indexed to a tetragonal lattice, exhibit amazing variation in the preferred orientation with respect to their shapes. Although XPS data indicate that wires and cubes have a strong SnO2 type signal, bipyramids interestingly exhibit both SnO and SnO2 signals and a correlation of the binding energy helps in understanding the growth kinetics of such submicron structures. The. results suggest that the bipyramids are formed because of the vapor-solid process (VS) while wires and cubes are formed by the vapor-liquid-solid (VLS) progression.</p>1 aRamgir, N., S.1 aMulla, Imtiaz, S.1 aVijayamohanan, K., P.  uhttps://library.ncl.res.in/content/effect-ruo2-shape-selectivity-submicron-sized-sno2-structures-0
