Princeton reports single charge sensing in Quantum Dots

Professors Jason Petta and John Sturm, and co-workers at Princeton University have reported the detection of single charges in double quantum-dot structures. Hall measurements were performed on Si/SiGe heterostructures with epitaxy provided by LSRL. According to the authors, "By adjusting the growth parameters, we are able to achieve electron gases with charge densities 1–3E11/cm2 and mobilities i...
