Cross-hatch strain effects on SiGe quantum dots for qubit variability estimation
Luis Fabián Peña, Mitchell I. Brickson, Fabrizio Rovaris +11
SiGe heterostructures integrated with Si via virtual substrate (VS) growth are promising hosts for spin qubits. While VS growth targets plastic relaxation, residual cross-hatch str…
