Measuring kinetic inductance and superfluid stiffness of two-dimensional superconductors using high-quality transmission-line resonators
Mary Kreidel, Xuanjing Chu, Jesse Balgley +8
The discovery of van der Waals superconductors in recent years has generated a lot of excitement for their potentially novel pairing mechanisms. However, their typical atomic-scale…
Superfluid stiffness of twisted multilayer graphene superconductors
Abhishek Banerjee, Zeyu Hao, Mary Kreidel +12
The robustness of the macroscopic quantum nature of a superconductor can be characterized by the superfluid stiffness, , a quantity that describes the energy required to vary…
Imaging Andreev Reflection in Graphene
S. Bhandari, G. -H. Lee, K. Watanabe +3
Coherent charge transport along ballistic paths can be introduced into graphene by Andreev reflection, for which an electron reflects from a superconducting contact as a hole, whil…
Imaging the Flow of Holes from a Collimating Contact in Graphene
Sagar Bhandari, Mary Kreidel, Alexander Kelser +5
A beam of holes formed in graphene by a collimating contact is imaged using a liquid-He cooled scanning probe microscope (SPM). The mean free path of holes is greater than the devi…
Imaging electron flow from collimating contacts in graphene
Sagar Bhandari, Gil-Ho Lee, Kenji Watanabe +3
The ballistic motion of electrons in graphene encapsulated in hexagonal boron nitride (hBN) promises exciting opportunities for electron-optics devices. A narrow electron beam is d…
Imaging electron flow and quantum dot formation in MoS2 nanostructures
Sagar Bhandari, Ke Wang, Kenji Watanabe +3
Among newly discovered two-dimensional (2D) materials, semiconducting ultrathin sheets of MoS2 show potential for nanoelectronics. However, the carrier mobility in MoS2 is limited…
