Sharp periodic Ge concentration modulations beyond the conduction band valley wavevector in nuclear spin-free Si quantum wells
Ivo Rahlff, Carsten Richter, Martin Schmidbauer +13
Periodic Ge modulations within strained Si quantum wells in SiGe heterostructures offer a route to deterministically enhance conduction-band valley splitting in Si, a key requireme…
Increasing valley splitting in Si/SiGe by practically achievable heterostructure profiles
Lukas Cvitkovich, Peter Stano, Dominique Bougeard +2
Silicon spin qubits are marred by the valley degeneracy of the conduction band. In a nanodevice, the degeneracy is lifted by interfaces and alloy disorder, but the resulting valley…
Disorder-independent hole spin manipulation by hopping
Biel Martinez, Ana Sempere-Sanchis, José C. Abadillo-Uriel +1
Spin manipulation by hopping has recently emerged as a promising strategy to control hole spins in quantum dots using exclusively baseband control, thereby mitigating power dissipa…
