Density dependence of the excitation gaps in an undoped Si/SiGe double-quantum-well heterostructure

D. Chen, S. Cai, N. -W. Hsu +7

We report low-temperature magneto-transport measurements of an undoped Si/SiGe asymmetric double quantum well heterostructure. The density in both layers is tuned independently uti…
