Vortex dynamics differences in YBaCuO at low temperatures for H||ab planes due to twin boundary pinning anysotropy
S. Salem-Sugui, A. D. Alvarenga, M. Friesen +5
We measured magnetization, M, of a twin-aligned single crystal of YBa2Cu 3Ox (YBaCuO), with Tc = 91 K, as a function of temperature, T, and magnetic field, H, with H applied along…
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…
