论文摘要
我们研究了几个单层库酸酯的材料参数,包括具有氟化缓冲层的层,目的是识别可能的高温超导体。为了评估材料参数,我们使用Wannierization技术和受约束的随机相位近似。使用波动交换近似研究了获得的单频哈伯德模型。几个铜岩之间的比较揭示了未知的高$ t _ {\ text {c}} $超导体。在GA,Al和CD化合物中,与HG1201相比,具有更高的$ t _ {\ text {c}} $超导性的可能性。
We investigated the material parameters of several single-layer cuprates, including those with fluorinated buffer layers, with the aim of identifying possible high-temperature superconductors. To evaluate the material parameters, we use the Wannierization techniques and the constrained random phase approximation. The obtained single-band Hubbard models are studied using the fluctuation-exchange approximation. Comparison among several cuprates reveals unknown high-$T_{\text{c}}$ superconductors. In, Ga, Al, and Cd compounds in particular show the potential to exhibit higher-$T_{\text{c}}$ superconductivity than Hg1201.
