Associate Professor

Research:

The research in my group is primarily focused on studying transport in semiconductor nanowires of different narrow bandgap materials such as InAs, InSb, GaSb, InP and their alloys. Here we explore the electronic structure of novel crystal phases, and how these phases can be used in device structures and for transport physics.
One particular focus is quantum dots (artificial atoms) and coupled quantum dots (artificial molecules). We have developed a new method to create tunable coupled quantum dots with extremely strong confinement, which are ideal for exploring electron interactions and spin physics. 
Ongoing work involves exploring Kondo physics of coupled dots, quantum ring formation and orbital enhanced g-factors, coupling to ferromagnetic and superconducting contacts

Ever wondered what happens if you couple two quantum dots in two points? No? Well we figured it out anyway, and it is pretty interesting... (https://doi.org/10.1038/s41467-019-13583-7)
