文摘

Lattice mismatch and interfacial strain in quantum dots (QDs). Applying interfacial strain in effective mass approximation (EMA) method. Theoretically calculated capped core size in core/shell (multishell) quantum dots. Deposited shell (multishell) effects on structural and optical properties of the core in QDs. Lattice mismatch and interfacial strain effect on capped core size changes.
