Electron–phonon interaction in In-induced structures on Si(111) from first-principles

Abstract

Electron–phonon interaction in the Si(111)-supported rectangular phases of In is investigated within the density-functional theory and linear-response.

Electron–phonon coupling and superconductivity in a 2D Tl–Pb compound on Si(111)

“…The discovery of superconductivity was followed by a number of theoretical works which focused on the strength of the electronphonon (e-ph) interaction and the critical temperature of superconductivity in Pb/Si(111) and In/Si(111) systems. 9,[14][15][16][17] The experimental findings have also stimulated research activity on exploring other ultrathin superconductors, among them, a surface compound formed by metallic adsorbates, Tl and Pb, on Si(111) and Ge(111) surfaces. [11][12][13][18][19][20] Both heavy metals are bulk superconductors with strong spin-orbit coupling.…”

Energy dispersive anti-anharmonic effect in a Fano intervened semiconductor: revealed through temperature and wavelength-dependent Raman scattering

“…Fano interaction 1–5 is a phenomenon in science that appears in various systems from rarer gases to semiconductors and superconductors and gets manifested in different ways. Fano interaction 6 occurs when there is an interference between the discrete state and a degenerate continuum of states.…”
