Speaker: Alisa Danilenko (NYU) Title: Bound states and disorder in InAs/Al hybrid heterostructures Abstract: Two dimensional superconductor-semiconductor hybrid heterostructures have been utilized in a range of quantum devices, from voltage tunable gatemon qubits to numerous attempts at realizing topological phases. It is becoming clear that the presence of disorder in these structures plays a key role in any experiment involving them. In this talk, I will give a brief overview of several tunneling spectroscopy experiments which contribute to an experimental toolkit, allowing the extraction of a wealth of information regarding bound states in these structures. I will then delve into our current efforts to study disorder in these structures directly, characterizing a series of heterostructure growths. I will consider multiple avenues for pinpointing and quantifying disorder, including density scaling, level broadening, and apparent metal to insulator transitions. I will conclude by discussing strategies for improved material growth and sample preparation based on these results.
