Personal profile

Research

The research in my group is primarily focused on studying transport in semiconductor nanowires of materials such as InAs, GaSb and their alloys. We explore the electronic structure of novel crystal phases, and how these phases can be used in devices and for transport physics. One particular focus is quantum dots (artificial atoms) and coupled quantum dots (artificial molecules). We have developed a method to create coupled quantum dots with extremely strong confinement, which are ideal for exploring electron interactions and spin physics. Ongoing work involves exploring spin-orbit interaction in quantum dots with rotational symmetry (quantum rings), and quantum dots coupled to superconductors.

The gallery reel below shows examples of various research output. If you click on a picture, you will get a description and in some cases also see an animation.
