(color online) A schematic diagram of an n–i–Schottky device. (b) Contour plot of the PL spectra of a single QD as a function of bias voltage from −0.5 V to +0.5 V with different magnetic fields from 0 T to 9 T in Faraday geometry. (c) PL spectra of X, X2−, and X3− as a function of applied magnetic field from 0 T to 9 T with bias voltage at −0.5 V, 0 V, and +0.5 V, respectively. (d) The integrated intensities of X, X2−, and X3− as a function of the applied magnetic field with different bias voltages.[20]
