X-ray diffraction analysis of LT-GaAs multilayer structures
Multilayer structures of low-temperature-grown GaAs(LT-GaAs) into which ultra-thin layers containing excess As are periodically introduced are grown by molecular beam epitaxy. The concentration of excess As in the ultra-thin layers is determined by the analysis of the intensity [...]

What are Silicon Wafer Flats?
PAM XIAMEN offers Silicon Wafer Flats
Since Silicon Wafers look basically the same! Flats are cut into the edge of the wafers so users could determine the wafer’s dopant-type and orientation.

Abstract
Nanostructured surfaces can be broadly defined as substrates in which the typical features have dimensions in the range 1–100 nm (although the upper limit of 100 nm may be relaxed to greater sizes in some cases, depending on the material and the specific property being investigated). [...]
