The interplay of phonon and exciton-mediated superconductivity in hybrid semiconductor-superconductor structures
arXiv:1802.01348 · doi:10.1103/PhysRevLett.120.107001
Abstract
We predict a strong enhancement of the critical temperature in a conventional Bardeen-Cooper-Schrieffer (BCS) superconductor in the presence of a bosonic condensate of exciton-polaritons. The effect depends strongly on the ratio of the cutoff frequencies for phonon and exciton-polariton mediated BCS superconductivity, respectively. We also discuss a possible design of hybrid semiconductor-superconductor structures suitable for the experimental observation of such an effect.
