SPICE Workshop on Non-equilibrium Quantum Materials Design, June 27th - 29th 2023
Susanne Stemmer
In this talk, we will discuss the synthesis of high-quality thin films of cadmium arsenide (Cd3As2), which we grow by molecular beam epitaxy. Cd3As2 is known to belong to a class of topological materials known as three-dimensional Dirac semimetals, but, as we will discuss in this presentation, in thin films it can be tuned between a variety of topological phases. We will discuss the evolution of the electronic states of Cd3As2 films as their thickness is scaled. We show that magnetotransport studies can distinguish between the different topological phases. We will also discuss hybrid structures with superconductors that are an attractive route towards a topological superconductor.
