However, accurately determining the doping level remains a significant challenge due to a complex interplay of factors and limitations in various measurement techniques. In particular, in Bi$_{2}$Sr$_2$CuO$_{6+\\delta}$ and Bi$_2$Sr$_2$CaCu$_2$O$_{8+\\delta}$, where the mobile carriers are introduced by non-stoichiometric oxygen $\\delta$, the determination has been extremely problematic.
