MnBi2Te4 (MBT) is a prototype of magnetic topological insulators (TI). The MBT exhibits a class of exotic quantum phases at higher temperatures than that of the doped magnetic TI—the type of exotic phases changes with the number of septuple layers. As the temperature can make these phases fragile and electron-phonon interactions significantly increase with temperature, we investigate the septuple layer-dependent electron-phonon interactions at the surface of MBT at different temperatures. In this presentation, we will discuss this in detail.
