## Abstract In the framework of the hydrogen plasma model the semiconductor is considered as a system of donors and electrons in a uniform medium. A recently developed quantumβstatistical theory of hydrogen plasmas in thermal equilibrium is applied to this simple model; the lowering of the activati
A molar ratio of 2: 2:1 : 2 for Bi, Sr, Ca and Cu, respectively, showed impurity phases after the completion of the synthesis process described here. The sample was decomposed by high-temperature annealing under nitrogen and then the Bi-2212 phase was reformed by reoxygenation but the original impur
