a-e, Charge stability diagrams as a function of the DQD gate voltages \({V}_{{{\rm{G}}}_{1}}-{V}_{{{\rm{G}}}_{2}}\). The multi-electron QD bias \({V}_{{G}_{{\rm{S}}}}\) is varied in each panel, defined with respect to \({V}_{{{\rm{G}}}_{{\rm{S}}}}^{{\rm{casc}}}\), the bias where the conditions for cascade are observed, shown in panel c. This is the bias utilized in the main text of the manuscript. Similar data for additional devices can be found in Supplementary Section 2. f-j, Simulated charge stability diagrams using the methods described in Supplementary Section 4. k-o Schematic depiction of the electrochemical levels for the corresponding bias conditions, arranged column-wise.
