论文摘要
为了为基于H的超导体实验提出新建议，我们提出了一个理论框架，以理解应用电场对压力氢化物超导体的影响。我们在压力$ p $的材料中，当它具有绝缘子 - 渗透器的过渡时，在相应的超导临界温度$ t_ {cr} $上研究了一种材料。该理论表明，应用的电场穿透了材料，并迫使库珀对凝结凝结物。如果一个人应用电场然后升高温度，该理论预测了新的临界温度$ t^{el} _ {cr} $高于$ t_ {cr} $。因此，如果我们施加电场而不是增加压力，则系统具有较高的超导临界温度。结果表明，在碳酸硫氢化物的价格为$ 234GPA $，接近但低于临界温度$ T_C = 283K $，使用足够强的电场，我们可以将超导临界温度接近300K。
In our desire to give a new suggestion for H-based superconductors experiments we present a theoretical framework for understanding the impact of an applied electric field on pressured hydride superconductors. We study a material at pressure $p$, when it possesses insulator-superconductor transition, at the respective superconducting critical temperature $T_{cr}$. The theory shows the applied electric field penetrates the material and forces the Cooper pairs to Bose condensate. If one applies an electric field and then increases the temperature, the theory predicts novel critical temperature $T^{el}_{cr}$ higher than $T_{cr}$. Therefore, the system has a higher superconducting critical temperature if we apply an electric field instead of increasing the pressure. The result shows that in the case of carbonaceous sulfur hydride at $234Gpa$ and near but below critical temperature $T_c=283K$, applying a sufficiently strong electric field, we can bring the superconducting critical temperature close to 300K.
