High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. Díez-Carlón, M. Cárdenes Wuttig, N. Wei +7
Magnetic fields generally suppress phase-coherent Josephson transport, limiting superconducting interferometry to relatively low fields. Here we show that moiré-engineered graphene…
Revealing electron-electron interactions in graphene at room temperature with the quantum twisting microscope
M. Lee, I. Das, J. Herzog-Arbeitman +20
The Quantum Twisting Microscope (QTM) is a groundbreaking instrument that enables energy- and momentum-resolved measurements of quantum phases via tunneling spectroscopy across twi…
Probing the flat-band limit of the superconducting proximity effect in Twisted Bilayer Graphene Josephson junctions
A. Diez-Carlon, J. Diez-Merida, P. Rout +13
While extensively studied in normal metals, semimetals and semiconductors, the superconducting (SC) proximity effect remains elusive in the emerging field of flat-band systems. In…
Superconducting junctions with flat bands
P. Virtanen, R. P. S. Penttilä, P. Törmä +3
We analyze the properties of flat-band superconductor junctions that behave differently from ordinary junctions containing only metals with Fermi surfaces. In particular, we show h…
High-yield fabrication of bubble-free magic-angle twisted bilayer graphene devices with high twist-angle homogeneity
J. Diez-Merida, I. Das, G. Di Battista +7
Magic-angle twisted bilayer graphene (MATBG) stands as one of the most versatile materials in condensed-matter physics due to its hosting of a wide variety of exotic phases while a…
Ultra-low carrier density superconducting bolometers with single photon sensitivity based on magic-angle twisted bilayer graphene
G. Di Battista, K. C. Fong, A. Diez-Carlon +3
The superconducting (SC) state of magic-angle twisted bilayer graphene (MATBG) shows exceptional properties, as it consists of an unprecedentedly small electron (hole) ensemble of…
Critical role of device geometry for the phase diagram of twisted bilayer graphene
Zachary A. H. Goodwin, Valerio Vitale, Fabiano Corsetti +3
The effective interaction between electrons in two-dimensional materials can be modified by their environment, enabling control of electronic correlations and phases. Here, we stud…
