Reducing disorder in Ge quantum wells by using thick SiGe barriers

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Davide Costa, Lucas E. A. Stehouwer, Yi Huang, Sara Martí-Sánchez, Davide Degli Esposti | Summary: We investigate the disorder properties of two-dimensional hole gases in Ge/SiGe heterostructures grown on Ge wafers, using thick SiGe barriers to mitigate the influence of the semiconductor-dielectric interface. Across several heterostructure field […]

Nonlinearity of transparent SNS weak links decreases sharply with length

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Valla Fatemi, Pavel D. Kurilovich, Anton R. Akhmerov, Bernard van Heck, | Summary: Superconductor-normal material-superconductor (SNS) junctions are being integrated into microwave circuits for fundamental and applied research goals. The short junction limit is a common simplifying assumption for experiments with SNS junctions, but this limit […]
