It has been discovered as a germanium crystal grows into a large monocrystalline ingot, the ingot tends to grow in the form of an octahedron having flat areas on its surface that are parallel to the [111] crystallographic plane.

There is a marked variation with crystal orientation of the many well-known etchants for germanium. For example, some etchants (like CP-4) only form etch pits at dislocation sites when the surface is within a few degrees of (111) or (100).

The favored <110> growth direction was attributed to the crystallographic faceting of low‐energy {111} and {100} planes on the initial nucleus crystal and the exposed nanowire sidewall surfaces. Electron diffraction patterns of individual nanowires exhibited forbidden 1/3 {422} reflections due to incomplete {111} surface facets and the finite size of the nanowires.

Thus, the repeated, orientation-controlled synthesis of single-crystal monolayer graphene on the entire surface of a Si wafer using an H-terminated Ge buffer layer, in combination with complementary metal-oxide semiconductor–compatible etch-free transfer processes, may open up commercial realization of various functional devices based on single-crystal graphene.

I found the crystal axis orientation first with Americium 241, a lower energy gamma source. Then, I used a higher energy source, Thorium 232, in conjunction with the only a few angular reference points to also calculate rise time. Also, I wrote code to process the data. The success of this method will be evaluated and discussed.

We present the first study of multiplication noise for three orientations of electric field in germanium avalanche photodiodes (APD’s). The directional differences of noise are found to be rather weak by the measurements using a He‐Ne laser (6328 Å). The differences obtained, 0.5 dB, were comparable in value to the experimental errors.
