Fabrication of undoped AlGaAs/GaAs electron quantum dots
Andrew M. See, Oleh Klochan, Adam P. Micolich +3
We have fabricated a quantum dot single electron transistor based on an AlGaAs/GaAs heterostructure without any modulation doping. Our device is very stable from an electronic pers…
A triple quantum dot in a single wall carbon nanotube
K. Grove-Rasmussen, H. I. Jørgensen, T. Hayashi +2
A top-gated single wall carbon nanotube is used to define three coupled quantum dots in series between two electrodes. The additional electron number on each quantum dot is control…
Singlet-Triplet Physics and Shell Filling in Carbon Nanotube Double Quantum Dots
H. Ingerslev Jørgensen, K. Grove-Rasmussen, K. -Y. Wang +4
An artifcial two-atomic molecule, also called a double quantum dot (DQD), is an ideal system for exploring few electron physics. Spin-entanglement between just two electrons can be…
Fabry-Perot interference, Kondo effect and Coulomb blockade in carbon nanotubes
K. Grove-Rasmussen, H. I. Jørgensen, P. E. Lindelof
High quality single wall carbon nanotube quantum dots have been made showing both metallic and semiconducting behavior. Some of the devices are identified as small band gap semicon…
Electric-field controlled spin reversal in a quantum dot with ferromagnetic contacts
J. R. Hauptmann, J. Paaske, P. E. Lindelof
Manipulation of the spin-states of a quantum dot by purely electrical means is a highly desirable property of fundamental importance for the development of spintronic devices such…
Critical Current 0- Transition in Designed Josephson Quantum Dot Junctions
H. Ingerslev Jørgensen, T. Novotný, K. Grove-Rasmussen +2
We report on quantum dot based Josephson junctions designed specifically for measuring the supercurrent. From high-accuracy fitting of the current-voltage characteristics we determ…
