Crystalline Germanium Josephson Junctions
Frederik H. Knudsen, Axel Leblanc, Patrick J. Strohbeen +8
Conventional superconducting quantum electronics rely on well-established Josephson junctions made of Al/AlO where the weak link AlO is amorphous and is believed to hos…
Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
Epitaxial stabilization of magnetic GdAuSb/LaAuSb superlattices
Patrick J. Strohbeen, Soohyun Im, Tamalika Samanta +7
We report the epitaxial stabilization of GdAuSb films and GdAuSb/LaAuSb superlattices via molecular beam epitaxy on (0001)-oriented AlO substrates. GdAuSb crystallize i…
Superconductivity in Substitutional Ga-Hyperdoped Ge Epitaxial Thin Films
Julian A. Steele, Patrick J. Strohbeen, Carla Verdi +12
Doping-induced superconductivity in group IV elements may enable quantum functionalities in material systems accessible with well-established semiconductor technologies. Non-equili…
Molecular beam epitaxy growth of superconducting tantalum germanide
Patrick J. Strohbeen, Tathagata Banerjee, Aurelia M. Brook +7
Developing new material platforms for use in superconductor-semiconductor hybrid structures is desirable due to limitations caused by intrinsic microwave losses present in commonly…
Machine learning analysis of structural data to predict electronic properties in near-surface InAs quantum wells
Patrick J. Strohbeen, Abtin Abbaspour, Amara Keita +12
Semiconductor crosshatch patterns in thin film heterostructures form as a result of strain relaxation processes and dislocation pile-ups during growth of lattice mismatched materia…
