论文摘要
laalo $ _3 $/srtio $ _3 $接口的二维电子气（2DEG）以$ t _ {\ rm {c}} $作为电子浓度函数的圆顶形状的domelike形状展示了门可调超导性。在这里，我们建议可以将实验观察到的行为解释为超导差距的主要$延长$ $ s $ - $ wave $对称性的直接效果。我们的结果与实验数据非常吻合。如图所示，相关效应和自旋轨道耦合都没有显着影响我们分析中配对状态的物理图片。
The two-dimensional electron gas (2DEG) at the LaAlO$_3$/SrTiO$_3$ interface exhibits gate tunable superconductivity with a domelike shape of $T_{\rm{C}}$ as a function of electron concentration. Here, we propose that the experimentally observed behavior can be explained as a direct effect of the dominant $extended$ $s$-$wave$ symmetry of the superconducting gap. Our results agree very well with the experimental data. As shown, neither the correlation effects nor the spin-orbit coupling influence significantly the physical picture of the paired state steaming out from our analysis.
