D. Kumar et al., SILVER DOPING - A POTENTIAL MEANS TO GROW HIGH-QUALITY YBA2CU3O7-X THIN-FILMS ON BARE SAPPHIRE, Journal of superconductivity, 8(5), 1995, pp. 623-624
High quality Ag-doped YBa2Cu3O7-x (YBCO) thin films have been grown by
laser ablation on [($) over bar 1012] bare sapphire. This work demons
trates that Ag-doping can be used as very convenient means to realize
good quality YBCO films on highly coveted sapphire substrates for micr
owave applications of high T-c thin films.
