| 摘 要： | As a typical hole-doped cuprate superconductor, Bi2Sr2CaCu2O8+δ(Bi2212) carrier doping is mostly determined by its oxygen content. Traditional doping methods can regulate its doping level within the range of hole doping.Here we report the first application of CaH2 annealing method in regulating the doping level of Bi2212. By continuously controlling the anneal time, a series of differently doped samples can be obtained. The combined experime...
