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…

Light effective hole mass in undoped Ge/SiGe quantum wells
M. Lodari, A. Tosato, D. Sabbagh +5
We report density-dependent effective hole mass measurements in undoped germanium quantum wells. We are able to span a large range of densities ( cm) in…

Low disordered, stable, and shallow germanium quantum wells: a playground for spin and hybrid quantum technology
A. Sammak, D. Sabbagh, N. W. Hendrickx +10
Buried-channel semiconductor heterostructures are an archetype material platform to fabricate gated semiconductor quantum devices. Sharp confinement potential is obtained by positi…
