(a) Grey-scale plot of the differential conductance vs and at . Diagonal white lines show SCR conditions: , where , 2. The horizontal dotted line shows the MPR condition . Vertical dotted lines represent the optical phonon resonance (OPR) condition , where , 2. The OPR condition corresponds to dissipation of energy through LO phonon emission. (b)–(c) Schematic diagram of the inter-WSL level electron hopping process corresponding to the SCR and MPR conditions.
