Ma. Subramanian, IODINE INTERCALATION IN BI2SR2Y0.5CA0.5CU2O8- EVIDENCE OF HOLE TRANSFER FROM IODINE TO COPPER-OXYGEN SHEETS(DELTA ), Journal of solid state chemistry, 110(1), 1994, pp. 193-195
We have successfully intercalated iodine between the Bi-O layers of th
e semiconducting Bi2Sr2Y0.5Ca0.5Cu2O8+delta. X-ray diffraction and the
rmogravimetric analysis confirmed the formation of a stage-1 intercala
ted compound, IBi2Sr2Y0.5Ca0.5Cu2O8+delta. Upon intercalation, the com
pound became superconducting, indicating there is a modest transfer of
holes from iodine located in Bi-O layers to Cu-O sheets. (C) 1994 Aca
