What is it about?
In this article we show how we can modulate the superconductivity of 2D layers using stattic electric field. Superconductivity in the extreme two-dimensional atomic layers has been suffered because of the strong affection dimensionality confinement on electron-phonon binding. Here, using first-principles method, we study the effect of applied perpendicular and parallel electric field on the strength of phonon renormalization and electron-phonon coupling in bi-layer MgB2 as a known 2D superconductor.

Why is it important?
it helps manipulataion of 2D layers vibronic correlation exploiting static electric field. Our study opens up the use of electric filed to probe and measure the variation amount of electron-phonon renormalization as a gauge in 2D superconductivity.
Perspectives
it provide a good feedback from electrical management of 2D vibronic correlation.
