Atomic-scale mechanism of enhanced electron-phonon coupling at the interface of MgB thin film
Xiaowen Zhang, Tiequan Xu, Ruochen Shi +7
In this study, we explore the heterointerface of MgB film on SiC substrate at atomic scale using electron microscopy and spectroscopy. We detect ~1 nm MgO between MgB and S…
