论文摘要
我们先前已经表明，在超导圆顶内观察到的粉碎液和富富的超导特征的大多数异常，以及圆顶在相图中的位置，不需要了解其电子结构的详细信息，但可以理解并在范围内进行了简单的框架来理解和置于模型范围内的框架。这一事实表明，范式的变化形成了我们对HTSC的理解。在本文中，我们提出了关于掺杂载体自定位的假设，提出了关于异源和异价掺杂的电子结构和二价掺杂的统一观点。在此表示中，在最初具有不同电子结构（Mott绝缘体和半学）的未木粉末和铁蛋白酶中，局部掺杂形成了具有相同电子结构的自动型激发型绝缘子的电子结构的渗透簇，其中具有超导配对的特定机制，具有遗传上的属性，该系统是属于遗传的系统。提出的模型包括一种机制，用于在异构和异价掺杂下生成其他自由载体，并可以预测其符号，在一般情况下，这与掺杂载体的符号不一致。
We have previously shown that most of the anomalies in the superconducting characteristics of cuprates and ferropnictides observed at dopant concentrations within the superconducting dome, as well as the position of the domes in the phase diagrams, do not require knowledge of the details of their electronic structure for explanation, but can be understood and calculated with high accuracy within the framework of a simple model describing the cluster structure of the superconducting phase. This fact suggests a change in the paradigm that forms our understanding of HTSC. In this paper, we propose a unified view on the transformation of the electronic structure of cuprates and ferropnictides upon heterovalent and isovalent doping, based on the assumption of self-localization of doped carriers. In this representation, in undoped cuprates and ferropnictides, which initially have different electronic structures (Mott insulator and semimetal), local doping forms percolation clusters with the same electronic structure of a self-doped excitonic insulator where a specific mechanism of superconducting pairing is implemented, which is genetically inherent in such a system. The proposed model includes a mechanism for generating additional free carriers under heterovalent and isovalent doping and makes it possible to predict their sign, which, in the general case, does not coincide with the sign of doped carriers.
