Valley-Free Silicon Fins Caused by Shear Strain
Valley-Free Silicon Fins Caused by Shear Strain
Electron spins confined in silicon quantum dots are promising candidates for large-scale quantum computers. However, the degeneracy of the conduction band of bulk silicon introduces additional levels dangerously close to the window of computational energies, where the quantum information can leak. The energy of the valley states-typically 0.1 meV-depends on …
