Interlayer electron-phonon coupling in Moire superlattices

ORAL

Abstract

Electron-phonon coupling is lying at the heart of many condensed matter phenomena. The van der Waals stacking of two-dimensional materials and the twisting-angle-controlled Moire superlattice offer new opportunities for studying and engineering interlayer electron-phonon coupling. I will present our infrared spectroscopy study of several graphene-based Moire superlattices, showing strong features of interlayer electron-phonon coupling. This coupling can be further tuned through controlling the Moire wavelength and gate electric fields.
