Interplay of spin-orbit coupling and trigonal crystal field enhances superconductivity in $LaAl{O}_3/KTa{O}_3$ (111)

Long Cheng, Jia Liu, Tongying Liu +10

In conventional superconductors, bulk physical properties typically degrade as the film thickness approaches the two-dimensional (2D) limit. Here in the (111) oriented LaAlO3/KTaO3…
