topograph for a gallium arsenide substrate is shown in Fig. 3. Each "bar" (of a lighter shade) is the image created by diffraction from one particular set of lattice planes, and, as such, may be identified by a particular set of Hiller indices. The size and shape of these images is merely a reproduction of the size and shape of the "footprint" of the incident xray beam on the specimen. The ...
· Gallium Arsenide (GaAs), Cadmium Sulfide (CdS), Gallium Nitride (GaN) and Gallium Arsenide Phosphide (GaAsP) are compound semiconductors.
