Silicon-germanium heterostructures have successfully hosted quantum dot qubits, but the intrinsic near-degeneracy of two lowest valley states poses an obstacle to high fidelity computing. We present a modification Si/SiGe heterostructure by inclusion spike in germanium concentration within well order increase splitting. The is grown chemical vapor deposition and magnetospectroscopy performed on gate-defined dots measure excited state spectrum. demonstrate large widely tunable splitting as...
