Nanosensing Backed by the Uncertainty Principle

Figure 12

(a) Semicircle shaped DQW, where the asymmetry is generated by a rectangular defect in the right QW. The defect height, , and width, , were varied, as indicated in the inset, while the radii and the dot interdistance are maintained constant (nm and nm). (b) Electron average position plotted against the electron spectrum of the asymmetric DQWs.
