ER spectra for different samples under investigation. (a) ER spectra for the reference sample (no Ge was deposited) as well as for the WL and QD samples measured at reverse bias Ub = 1.5 V. (b) Experimental ER spectrum (circles) and curve fit (solid lines) for the QD sample. The obtained values of the energies are represented by bars in the figure.
