文摘

Transition of inherently over-doped nature to optimally doped state. Optimum annealing temperature of Au diffusion-doped Bi-2212 inorganic materials. Increase in artificial disorders, distortions and defects with excess Au impurities. In-depth understanding of empirical relationship between disorders and transition temperatures. Determination of possibly maximum onset and offset critical temperature values.
