Morphologies of square shape spirals and (110) twins in spiral-grown Bi2Sr2CaCu2Oy, crystals

Journal Article


Abstract


  • It is reported that Bi2Sr2CaCu2Oy crystals were grown by a spiral growth mechanism if crystals were grown at KCl flux surface. It was observed that all the growth spirals have square shape with single and multiple spirals generated together if the growth temperatures are lower than 850°C. Furthermore, (110) growth twins were found to coexist with the square shape single or multiple spirals by polarized optical microscope. It is the coexistence of spiral growth and (110) growth twins that leads to the square shape of the growth spirals.
