Role of Quantum Confinement in Luminescence Efficiency of Group IV Nanostructures

E. G. Barbagiovanni, D. J. Lockwood, N. L. Rowell +7

Experimental results obtained previously for the photoluminescence efficiency (PL${}_{eff}$) of Ge quantum dots (QDs) are theoretically studied. A $\log$-$\log$ plot of PL${}_{eff}$ ve…
