Controllable valley splitting in silicon quantum devices
Srijit Goswami, K. A. Slinker, Mark Friesen +10
Silicon has many attractive properties for quantum computing, and the quantum dot architecture is appealing because of its controllability and scalability. However, the multiple va…
Quantum Dots and Etch-Induced Depletion of a Silicon 2DEG
L. J. Klein, K. L. M. Lewis, K. A. Slinker +8
The controlled depletion of electrons in semiconductors is the basis for numerous devices. Reactive-ion etching provides an effective technique for fabricating both classical and q…
Electron spin coherence in Si/SiGe quantum wells
J. L. Truitt, K. A. Slinker, K. L. M. Lewis +11
The mechanisms limiting the spin coherence time of electrons are of great importance for spintronics. We present electron spin resonance (ESR) and transport measurements of six dif…
Spectroscopy of Valley Splitting in a Silicon/Silicon-Germanium Two-Dimensional Electron Gas
Srijit Goswami, Mark Friesen, J. L. Truitt +8
The lifting of the two-fold degeneracy of the conduction valleys in a strained silicon quantum well is critical for spin quantum computing. Here, we obtain an accurate measurement…
Coulomb Blockade in a Silicon/Silicon-Germanium Two-Dimensional Electron Gas Quantum Dot
L. J. Klein, K. A. Slinker, J. L. Truitt +14
We report the fabrication and electrical characterization of a single electron transistor in a modulation doped silicon/silicon-germanium heterostructure. The quantum dot is fabric…
