Figure 2

Caption

White characters in figure show the number of electrons in each quantum dots. (a) Observed charge stability diagram. Three different slopes of the charge transition lines indicate formation of triple quantum dots. No transition line is observed in the lower left regime, which suggests these quantum dots are in few-electron regime. (b) QCA effect observed in ZnO quantum dots. Two electrons move at the same time when the number of electron changes from 022 to 113.
