Electron spin coherence in Si

Autor: Alexei M. Tyryshkin, J. L. Truitt, Friedrich Schäffler, Mark A. Eriksson, J. O. Chu, Stephen Aplin Lyon, Wolfgang Jantsch, Thomas Schenkel, Jeffrey Bokor, Susan Coppersmith

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 35:257-263

We discuss pulsed electron spin resonance measurements of electrons in Si and determine the spin coherence from the decay of the spin echo signals. Tightly bound donor electrons in isotopically enriched 28 Si are found to have exceptionally long spin

Electron dynamics of an artificial atom probed by pulsed microwave spectroscopy

Autor: D.W. van der Weide, Hua Qin, J. L. Truitt, Robert H. Blick, Karl Eberl

Publikováno v: Nanotechnology. 14:60-64

Using picosecond millimetre-wave impulses we probe the electronic structure and dynamics of electrons in a single quantum dot—the artificial atom—which is essential for understanding their applications such as computational elements and detectors

Probing a single quantum dot by pulsed and continuous microwave radiation

Autor: J. L. Truitt, Robert H. Blick, D.W. van der Weide, Hua Qin

Publikováno v: Physica B: Condensed Matter. 314:444-449

Using both picosecond millimeter-wave impulses and continuous microwave radiation, we probe the electronic structure and dynamic response of single-electron tunneling in structured quantum dots, essential for understanding their applications as compu

Coulomb blockade in a silicon/silicon–germanium two-dimensional electron gas quantum dot

Autor: J. L. Truitt, K. A. Slinker, K. L. M. Lewis, John A. Ott, Mark A. Eriksson, Srijit Goswami, Robert Joynt, J. O. Chu, D.W. van der Weide, Levente Klein, Susan Coppersmith, Patricia M. Mooney, Donald E. Savage, Max G. Lagally, Mark Friesen, Robert H. Blick, Charles Tahan

Publikováno v: Applied Physics Letters. 84:4047-4049

We report the fabrication and electrical characterization of a single electron transistor in a modulation doped silicon/silicon-germanium heterostructure. The quantum dot is fabricated by electron beam lithography and subsequent reactive ion etching.
