Density dependence of the excitation gaps in an undoped Si/SiGe double-quantum-well heterostructure
D. Chen, S. Cai, N. -W. Hsu +7
We report low-temperature magneto-transport measurements of an undoped Si/SiGe asymmetric double quantum well heterostructure. The density in both layers is tuned independently uti…
Broadband microwave spectroscopy of semiconductor nanowire-based Cooper-pair transistors
Alex Proutski, Dominique Laroche, Bas van 't Hooft +4
The Cooper-pair transistor (CPT), a small superconducting island enclosed between two Josephson weak links, is the atomic building block of various superconducting quantum circuits…
Observation of the 4-periodic Josephson effect in indium arsenide nanowires
Dominique Laroche, Daniël Bouman, David J. van Woerkom +9
Quantum computation by non-Abelian Majorana zero modes (MZMs) offers an approach to achieve fault tolerance by encoding quantum information in the non-local charge parity states of…
Atomic-layer doping of SiGe heterostructures for atomic-precision donor devices
E. Bussmann, John King Gamble, J. C. Koepke +9
As a first step to porting scanning tunneling microscopy methods of atomic-precision fabrication to a strained-Si/SiGe platform, we demonstrate post-growth P atomic-layer doping of…
Density-controlled quantum Hall ferromagnetic transition in a two-dimensional hole system
T. M. Lu, L. A. Tracy, D. Laroche +5
Quantum Hall ferromagnetic transitions are typically achieved by increasing the Zeeman energy through in-situ sample rotation, while transitions in systems with pseudo-spin indices…
Mechanical Flip-Chip for Ultra-High Electron Mobility Devices
K. Bennaceur, B. A. Schmidt, S. Gaucher +6
Electrostatic gates are of paramount importance for the physics of devices based on high-mobility two-dimensional electron gas (2DEG) since they allow depletion of electrons in sel…
