Large Stark tuning of donor electron spin quantum bits in germanium
A. J. Sigillito, A. M. Tyryshkin, J. W. Beeman +3
Donor electron spins in semiconductors make exceptional quantum bits because of their long coherence times and compatibility with industrial fabrication techniques. Despite many ad…
Electron spin coherence of shallow donors in natural and isotopically enriched germanium
A. J. Sigillito, R. M. Jock, A. M. Tyryshkin +4
Germanium is a widely used material for electronic and optoelectronic devices and recently it has become an important material for spintronics and quantum computing applications. D…
Electrically driven photonic crystal nanocavity devices
Gary Shambat, Bryan Ellis, Jan Petykiewicz +6
Interest in photonic crystal nanocavities is fueled by advances in device performance, particularly in the development of low-threshold laser sources. Effective electrical control…
Thermal Expansion of Germanium Isotopes at Low Temperature
R. Colella, B. Reinhart, E. Alp +1
The focus of this paper is the vanishing of the thermal expansion in certain diamond-like semiconductors. In silicon becomes zero at T = 122. K. In germanium the situation is less…
A Schottky top-gated two-dimensional electron system in a nuclear spin free Si/SiGe heterostructure
J. Sailer, V. Lang, G. Abstreiter +8
We report on the realization and top-gating of a two-dimensional electron system in a nuclear spin free environment using 28Si and 70Ge source material in molecular beam epitaxy. E…
Debris disks around Sun-like stars
D. E. Trilling, G. Bryden, C. A. Beichman +7
We have observed nearly 200 FGK stars at 24 and 70 microns with the Spitzer Space Telescope. We identify excess infrared emission, including a number of cases where the observed fl…
