Tunneling Control of Transmission Coefficient and Group Index in a Quantum Dot Nanostructure
Figure 1
Schematic band structure and level configuration of a double QD system. (a) Without a gate voltage, electron tunneling is weak. (b) With applied gate voltage, conduction and valence band levels get into resonance, increasing their coupling. (c) Levels taken into account by Hamiltonian model and the basis of states used to describe it.
