Reducing strain fluctuations in quantum dot devices by gate-layer stacking
Collin C. D. Frink, Talise Oh, E. S. Joseph +5
Nanofabricated metal gate electrodes are commonly used to confine and control electrons in electrostatically defined quantum dots. However, these same gates impart strain-induced p…
Coupling conduction-band valleys in SiGe heterostructures via shear strain and Ge concentration oscillations
Benjamin D. Woods, Hudaiba Soomro, E. S. Joseph +4
Engineering conduction-band valley couplings is a key challenge for Si-based spin qubits. Recent work has shown that the most reliable method for enhancing valley couplings entails…
Practical Strategies for Enhancing the Valley Splitting in Si/SiGe Quantum Wells
Merritt P. Losert, M. A. Eriksson, Robert Joynt +4
Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two l…
