Enhanced Valley Splitting in Si Layers with Oscillatory Ge Concentration
Yi Feng, Robert Joynt
The valley degeneracy in Si qubit devices presents problems for their use in quantum information processing. It is possible to lift this degeneracy by using the Wiggle Well archite…

SiGe quantum wells with oscillating Ge concentrations for quantum dot qubits
Thomas McJunkin, Benjamin Harpt, Yi Feng +10
Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or tunable energy splittings of the valley states associated with degenerate conduction band mi…
