Abstract

Author(s): Baruch Rosenstein, B. Ya. Shapiro, I. Shapiro, and Dingping LiPairing in one-atomic-layer-thick two-dimensional electron gas (2DEG) by a single flat band of high-energy longitudinal optical phonons is considered. The polar dielectric SrTiO_{3} (STO) exhibits such an energetic phonon mode and the 2DEG is created both when one unit cell FeSe layer is grown on it…[Phys. Rev.
