Pronounced Site Preference in Cr-Doped Mn-Based M-Type Hexaferrites and Its Chemical Origins
Dylan Correll, Susheng Tan, Evan Wang +1
Cation distribution plays a critical role in determining the properties of crystalline oxides. Understanding the chemical factors that govern cation distribution is therefore essen…
Cryogenic growth of aluminum: structural morphology, optical properties, superconductivity and microwave dielectric loss
Wilson J. Yánez-Parreño, Teun A. J. van Schijndel, Anthony P. McFadden +7
We explore the molecular beam epitaxy synthesis of superconducting aluminum thin films grown on c-plane sapphire substrates at cryogenic temperatures of 6 K and compare their behav…
Double quantum dots with quenched charging energy in PbTe nanowires
Seth Byard, Maksim Gomanko, Adam Raynolds +4
We investigate double quantum dots defined by electrostatic gating in semiconductor PbTe nanowire devices. We perform transport measurements to obtain charge stability diagrams dis…
Sn-InAs nanowire shadow-defined Josephson junctions
Amritesh Sharma, An-Hsi Chen, Connor P. Dempsey +6
Interest in hybrid electronic devices for quantum science is driving the research into superconductor-semiconductor materials combinations. Here we study InAs nanowires coated with…
Role of a capping layer on the crystalline structure of Sn thin films grown at cryogenic temperatures on InSb substrates
A. -H. Chen, C. P. Dempsey, M. Pendharkar +8
Metal deposition with cryogenic cooling is widely utilized in the condensed matter community for producing ultra-thin epitaxial superconducting layers on semiconductors. However, a…
