Atomic-scale mechanism of enhanced electron-phonon coupling at the interface of MgB $_{2}$ thin film

Xiaowen Zhang, Tiequan Xu, Ruochen Shi +7

In this study, we explore the heterointerface of MgB $_{2}$ film on SiC substrate at atomic scale using electron microscopy and spectroscopy. We detect ~1 nm MgO between MgB $_{2}$ and S…

Possible Eliashberg-type superconductivity enhancement effects in a two-band superconductor MgB2 driven by narrow-band THz pulses

Sergei Sobolev, Amon Lanz, Tao Dong +12

We study THz-driven condensate dynamics in epitaxial thin films of MgB $_{2}$ , a prototype two-band superconductor (SC) with weak interband coupling. The temperature and excitation…
