Undoped accumulation-mode Si/SiGe quantum dots
Matthew G. Borselli, Kevin Eng, Richard S. Ross +11
We report on a quantum dot device design that combines the low disorder properties of undoped SiGe heterostructure materials with an overlapping gate stack in which each electrosta…

Measurement of valley splitting in high-symmetry Si/SiGe quantum dots
Matthew G. Borselli, Richard S. Ross, Andrey A. Kiselev +12
We have demonstrated few-electron quantum dots in Si/SiGe and InGaAs, with occupation number controllable from N = 0. These display a high degree of spatial symmetry and identifiab…
