摘要：

Reference dielectric function data for several common YBa2Cu3O7-delta (YBCO) substrate material shave been determined by spectroscopic ellipsometry over the range 250 nm - 750 nm. These materials include LaAlO3, BaZrO3, NdGaO3, 9.5 mol% Y2O3-ZrO2 (YSZ), LaSrGaO4 (LSGO), and (LaAlO3)(0.3)-(Sr2AlTaO6)(0.7) (LSAT). The precision of the data was confirmed by comparing SE determined data for SrTiO3 to published values. Agreement to the third decimal point was shown. These data have been used to characterize interfaces between YBCO and some of these materials by SE.
