de Haas-van Alphen spectroscopy and fractional quantization of magnetic-breakdown orbits in moiré graphene Open
Quantum oscillations originating from the quantization of the electron cyclotron orbits provide ultrasensitive diagnostics of electron bands and interactions in novel materials. We report on the first direct-space nanoscale imaging of the …

Imaging Chern mosaic and Berry-curvature magnetism in magic-angle graphene Open
Charge carriers in magic angle graphene come in eight flavors described by a combination of their spin, valley, and sublattice polarizations. When the inversion and time reversal symmetries are broken by the substrate or by strong interact…

Influence of Fabrication Processes on Transport Properties of Superconducting Niobium Nitride Nanowires Open
Fabrication of niobium nitride (NbN) superconducting nanowires based on focused ion beam (FIB) milling and electron beam lithography (EBL) is presented.The NbN films were deposited using reactive magnetron sputtering.Argon-to-nitrogen rati…
