Engineering Ge profiles in Si/SiGe heterostructures for increased valley splitting
Lucas E. A. Stehouwer, Merrit P. Losert, Maia Rigot +6
Electron spin qubits in Si/SiGe quantum wells are limited by the small and variable energy separation of the conduction band valleys. While sharp quantum well interfaces are pursue…

Reducing disorder in Ge quantum wells by using thick SiGe barriers
Davide Costa, Lucas E. A. Stehouwer, Yi Huang +4
We investigate the disorder properties of two-dimensional hole gases in Ge/SiGe heterostructures grown on Ge wafers, using thick SiGe barriers to mitigate the influence of the semi…
