Formation of Mn-rich interfacial phases in Co2FexMn1-xSi thin films
Ka Ming Law, Arashdeep S. Thind, Mihir Pendharkar +7
We report the formation of Mn-rich regions at the interface of Co2FexMn1-xSi thin films grown on GaAs substrates by molecular beam epitaxy (MBE). Scanning transmission electron mic…
Supercurrent through a single transverse mode in nanowire Josephson junctions
B. Zhang, Z. Li, H. Wu +6
Hybrid superconductor-semiconductor materials are fueling research in mesoscopic physics and quantum technology. Recently demonstrated smooth -Sn superconductor shells, due to t…
Competing Uniaxial Anisotropies in Epitaxial Fe Thin Films Grown on InAs(001)
James M. Etheridge, Joseph Dill, Connor P. Dempsey +6
We report on the interplay of two uniaxial magnetic anisotropies in epitaxial Fe thin films of varying thickness grown on InAs(001) as observed in ferromagnetic resonance experimen…
Zero-bias conductance peaks at zero applied magnetic field due to stray fields from integrated micromagnets in hybrid nanowire quantum dots
Y. Jiang, M. Gupta, C. Riggert +7
Many recipes for realizing topological superconductivity rely on broken time-reversal symmetry, which is often attained by applying a substantial external magnetic field. Alternati…
Sn/InAs Josephson junctions on selective area grown nanowires with in-situ shadowed superconductor evaporation
Aranya Goswami, Sanchayeta R. Mudi, Connor Dempsey +5
Superconductor-semiconductor nanowire hybrid structures are useful in fabricating devices for quantum information processing. While selective area growth (SAG) offers the flexibili…
Electronic structure of InSb (001), (110), and (111)B surfaces
Jason T. Dong, Hadass S. Inbar, Mihir Pendharkar +4
The electronic structure of various (001), (110), and (111)B surfaces of n-type InSb were studied with scanning tunneling microscopy and spectroscopy. The InSb(111)B (3x1) surface…
