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…
