Research Project Title:
Characterization of Hexagonal Boron Nitride for Graphene-Based Circuit QED
abstract:The rise of semiconductor systems as a potential quantum computing architecture has led to the merging of the superconductor and semiconductor platforms. Graphene presents itself as a leading candidate for these hybrid systems and thus requires the study of potential substrate materials. Hexagonal Boron Nitride (hBN) is, in the low-frequency regime, an excellent graphene substrate, demonstrating low interface impurity density and high graphene conductivity. However, the nature of hBN in the microwave regime remains unknown and must be understood to fully realize effective hybrid superconductor-semiconductor quantum computing devices. This work aims to study hBN in the high-frequency regime by using hBN as a dielectric for the capacitor of an LC resonator and measuring the hBN loss tangent.
The SuperUROP program provides a unique opportunity to gain experience working on my own research project in a specific subfield of applied Electrical Engineering applicable to my professional goals from start to finish while learning the invaluable skills of presentation and communication. I have worked with my SuperUROP supervisor for the past two years as a UROP student and am excited to pursue a more individual project in the coming year.
