Solid-state reaction synthesis of superconducting refractory-metal germanides for Ge/SiGe quantum devices

Posted by klaurent Delft

Kavli Affiliate: Giordano Scappucci | Summary:Solid-phase reactions offer a route to integrate superconductors into Ge/SiGe heterostructures, but forming high-quality superconducting layers near the buried Ge quantum well remains challenging. We investigate reactions of V, Ta, and Nb with elemental Ge and with the Si$_0.2$Ge$_0.8$ barrier of Ge/SiGe heterostructures at processing temperatures of 365-390 $^circ$C. Cross-sectional […]

Nuclear mass table in deformed relativistic Hartree-Bogoliubov theory in continuum, III: nuclei with $8 leq Z leq 120$

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:The mass table in the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) with the PC-PK1 density functional has been established for nuclei with $8 leq Z leq 120$, extended from the previous works for even-even nuclei [Zhang et al. (DRHBc mass table collaboration), At. Data Nucl. Data Tables 144, 101488 (2022)] […]
