Extended Data Fig. 4: HRTEM images show the random detachment process of Cu atoms at the crystalline Cu–amorphous interphase interface.
From: Atomic dynamics of electrified solid–liquid interfaces in liquid-cell TEM
In the schematic, the red and yellow sections represent crystalline Cu and the amorphous interphase, respectively. The yellow arrows point to the atoms at atomic step edges. The red arrow points to an atomic vacancy on the terrace.
