Effect of quantum Hall edge strips on valley splitting in silicon quantum wells
Brian Paquelet Wuetz, Merritt P. Losert, Alberto Tosato +10
We determine the energy splitting of the conduction-band valleys in two-dimensional electrons confined to low-disorder Si quantum wells. We probe the valley splitting dependence on…

Quantum transport properties of industrial Si/SiO
D. Sabbagh, N. Thomas, J. Torres +21
We investigate the structural and quantum transport properties of isotopically enriched Si/SiO stacks deposited on 300 mm Si wafers in an industrial CMOS fab. Hig…

The critical role of substrate disorder in valley splitting in Si quantum wells
Samuel F. Neyens, Ryan H. Foote, Brandur Thorgrimsson +11
Motivated by theoretical predictions that spatially complex concentration modulations of Si and Ge can increase the valley splitting in quantum wells, we grow and characterize Si/S…
