论文摘要
我们在实验中搜索实验性地观察到的野外诱导的超导体到禁区的过渡，以电子掺杂的srtio $ _ {3} $/laalo $ _ {3} $接口进行了分析，在理论上，在理论上非常非常分析，在理论上非常非常分析。 （2021））。使用具有强旋轨散射的2D电子气体模型，我们发现在零温度极限中，波动质量的田间诱导的未结合的生长以及随之而来的库珀对在中镜水坑中的差异使该系统驱动该系统以在高地位上使系统造成渗透性状态。 Application of this model to the gate-voltage tuned 2D electron system, created in the SrTiO$_{3}$/LaAlO$_{3}$ (111) interface at low temperatures, shows that, at sufficiently high fields, the DOS conductivity prevails over the paraconductivity, resulting in strongly enhanced magnetoresistance in systems with sufficiently small carriers density.库珀对的动力量子隧道闯入移动正常电子状态，以防止在零温度下发散，其中包含高场电阻的开始。
We search for the deep origin of the field-induced superconductor-to-insulator transitions observed experimentally in electron-doped SrTiO$_{3}$/LaAlO$_{3}$ interfaces, which were analyzed theoretically very recently within the framework of superconducting fluctuations approach (Phys. Rev. B $\bf{104}$, 054503 (2021)). Employing the 2D electron-gas model with strong spin-orbit scatterings, we have found that in the zero temperature limit, field-induced unbounded growth of the fluctuation mass, and consequent divergence of Cooper-pair density in mesoscopic puddles, drives the system to Boson insulating states at high fields. Application of this model to the gate-voltage tuned 2D electron system, created in the SrTiO$_{3}$/LaAlO$_{3}$ (111) interface at low temperatures, shows that, at sufficiently high fields, the DOS conductivity prevails over the paraconductivity, resulting in strongly enhanced magnetoresistance in systems with sufficiently small carriers density. Dynamical quantum tunneling of Cooper pairs breaking into mobile normal-electrons states, which prevent the divergence at zero temperature, contain the high-field resistance onset.
