Metal Single Crystals

Our metal single crystals are characterized by their outstanding high quality:

Mosaicity:

Mosaicity describes the deviation from the perfect structure of the crystal. It is an angular distribution which represents the orientation of individual crystallites in the crystal volume. A small angular distribution stands for a perfect crystal structure.

We achieve a mosaicity of <0.1° (typically < 0.05°) and can characterize the entire crystal volume with our own gamma diffractometer.

Orientation accuracy:

When using the surfaces, the precise alignment of the crystallographic axes to the surfaces is particularly important. We guarantee an orientation accuracy of <0.1° (on request <0.05°).

Surface conditioning:

After a few heating and sputtering cycles, the particularly gentle polish allows the direct examination and use of the up to several 1,000 nm wide, atomically smooth surface terraces. We guarantee a roughness (Ra) < 10 nm (usually 0.5 nm).

Geometry:

Specific measurement setups or applications require an individual dimensioning of the crystal. We can fulfill (almost) all wishes for the crystal geometry.
