掺铜氧化物和铁磷氧化物中的高温超导胶：面内Ginzburg高温超导夹层中的可移动CT激子
HTSC-glue in doped copper oxides and iron pnictides: mobile CT-excitons within in-plane Ginzburg HTSC-sandwich
摘要：
研究表明，当可动载流子的库珀配对是由特征能量高于声子的德拜能量的激子介导时，高温超导的Little-Ginzburg激子机制使铜酸盐和新型铁基超导体达到了高的超导转变临界温度。这种机制在这些掺杂化合物中的有效性是由于一系列平面Ginzburg HTSC-“三明治”：“绝缘体”-“金属”-“绝缘体”（条纹结构）在正常状态下低于起始赝能隙温度的导电平面中自然形成。这种面内高温超导“三明治”的外部“绝缘”板中的移动平面电荷转移（CT）激子的参数恰好在金斯伯格大约四十年前预测的最佳范围内。
英文摘要：
It is demonstrated that high critical temperature of superconducting transition in cuprates and new iron-based superconductors is reached because of the Little-Ginzburg exciton mechanism of HTSC when Cooper pairing of mobile charge carriers is mediated by excitons which characteristic energy is essentially higher than Debye one for phonons. The effectiveness of such mechanism in these doped compounds is provided due to a series of planar Ginzburg HTSC-'sandwiches': 'insulator'-'metal'- 'insulator' (stripe structure) naturally forming in conducting planes below the onset pseudogap temperature in the normal state. The parameters of mobile, planar charge-transfer (CT) excitons in outer 'insulating' plates of such in-plane HTSC-'sandwich' are exactly within the optimal range predicted by Ginzburg about forty years ago.
