Abstract (German)

Diese Doktorarbeit beschäftigt sich mit auf Kohlenstoffnanoröhren basierenden Doppelquantenpunkten, welche mit zwei normalleitenden und einem supraleitenden Kontakt verbunden sind. Indem wir unsere Proben als Cooper-Paar-Strahlteiler verwenden, können wir Nonlokale Andreev-Reflektion nachweisen. Wir injizieren dazu Cooper-Paare in den supraleitenden Kontakt und messen den differentiellen ...


Translation of the abstract (English)

We report on conductance measurements in carbon nanotube based double quantum dots connected to two normal electrodes and a central superconducting finger. By operating our devices as Cooper pair beam splitters, we provide evidence for Crossed Andreev Reflection (CAR). We inject Cooper pairs in the superconducting electrode and measure the differential conductance at both left and right arm. The ...
