Valley splitting in a Si/SiGe quantum point contact
L. M. McGuire, Mark Friesen, K. A. Slinker +2
We present the theory and measurement of valley splitting in a quantum point contact (QPC) in a modulation doped Si/SiGe heterostructure. Our measurements are performed on a submic…
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…
Elastically Relaxed Free-standing Strained-Si Nanomembranes
Michelle M. Roberts, Levente J. Klein, Don E. Savage +5
Strain plays a critical role in the properties of materials. In silicon and silicon-germanium, strain provides a mechanism for control of both carrier mobility and band offsets. In…
Quantum dots in Si/SiGe 2DEGs with Schottky top-gated leads
K A Slinker, K L M Lewis, C C Haselby +8
We report on the fabrication and characterization of quantum dot devices in a Schottky-gated silicon/silicon-germanium two-dimensional electron gas (2DEG). The dots are confined la…
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…
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…
