Incommensurate smectic phase in close proximity to the high-T c superconductor FeSe/SrTiO3

Incommensurate smectic phase in close proximity to the high-T c superconductor FeSe/SrTiO3

The relation between enhanced superconductivity in monolayer FeSe grown on SrTiO3 and the large nematicity in multilayer FeSe on SrTiO3 remains not well understood. Here, the authors observe a long-range smectic phase in bilayer FeSe films but vanishes in monolayer FeSe, providing a new instability...
