Atomic-layer doping of SiGe heterostructures for atomic-precision donor devices
E. Bussmann, John King Gamble, J. C. Koepke +9
As a first step to porting scanning tunneling microscopy methods of atomic-precision fabrication to a strained-Si/SiGe platform, we demonstrate post-growth P atomic-layer doping of…
Spectroscopy of multi-electrode tunnel barriers
A. Shirkhorshidian, John King Gamble, L. Maurer +8
Despite their ubiquity in nanoscale electronic devices, the physics of tunnel barriers has not been developed to the extent necessary for the engineering of devices in the few-elec…
Effects of charge noise on a pulse-gated singlet-triplet qubit
Zhenyi Qi, X. Wu, D. R. Ward +11
We study the dynamics of a pulse-gated semiconductor double quantum dot qubit. In our experiments, the qubit coherence times are relatively long, but the visibility of the quantum…
