Streamlining twisted bilayer graphene measurements

Twisted bilayer graphene (TBG) has emerged as a promising platform for studying strongly correlated physics. When the twist angle is near the magic angle of approximately one degree, transport measurements have revealed a host of interesting phenomena including correlated insulating states, superconductivity, and ferromagnetism. However, fabricating and effectively measuring TBG samples remains challenging. The twist angle varies widely from sample to sample, and even from contact to contact within the same sample. In this work, I present a few tools we have used in order to streamline the process of making and measuring TBG samples, along with some interesting results encountered along the way.
