title = "Tunable tunnel and exchange couplings in double quantum dots",
abstract = "We prepare a novel double dot device in a hybrid vertical-lateral geometry to study the electronic configurations of the tunnel-coupled and exchange-coupled states. In this device two two-dimensional quantum dots coupled side by side, and current flows vertically. From transport measurements we derive important parameters such as the inter- and mtra-dot Coulomb energies, the tunnel coupling energy and the potential detuning between the two dots to influence the electronic configurations in a double dot. Thus we confirm the formation of the Heitler-I.ondon two-electron state in the weak tunnel coupling regime, and also find that the tunnel and exchange couplings are tunable with coupling gate voltage and magnetic field.",
