Fewer interfaces, longer coherence: inverting the multi-shell design rule for quantum-information colloidal quantum dots
Cascaded type-II core/shell/shell colloidal quantum dots are widely studied as a route to extended radiative lifetimes, suppressed Auger losses, and tunable near-infrared emission. To test whether the same architecture remains advantageous for coherence-limited quantum-information applications, the cascaded core/shell/...
