We present analysis of measurements on a triple quantum dot with a two path setup. The electron transport along both paths is recorded as well as charging data measured with a quantum point contact. The results are compared with an electrostatic mode

Results of combined experimental and theoretical studies of transport spectra of a quantum dot in a magnetic field are reported. In the linear regime, the observed oscillatory behavior of the conductance peaks with varying magnetic field is interpret

In recent years several attempts have been made to fabricate coupled quantum dots as a crucial element of quantum computing devices. One important challenge is to achieve a reliable control of the interdot tunneling. For this purpose we have combined

We present transport measurements on a lateral triple quantum dot made with local anodic oxidation on a GaAs/AlGaAs heterostructure. The device is formed in a star like geometry with each dot connected to the other two. Three leads are used to measur

We present transport measurements on a lateral triple quantum dot with a star-like geometry and one lead attached to each dot. [1] The system is studied in a regime close to established quadruple points, where all three dots are in resonance. The spe

We present a lateral quantum dot device which has a tunable number of quantum dots. Depending on easily tunable gate voltages, one, two or three quantum dots are found. They are investigated in transport and charge detection. © 2013 AIP Publishing L

The electronic states of lateral many electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb blockade peaks are measured. A zig-zag pattern is found as it

We present an advanced lateral triple quantum dot made by local anodic oxidation. Three dots are coupled in a starlike geometry with one lead attached to each dot thus allowing for multiple path transport measurements with two dots per path. In addit
