X-ray diffraction characterization of multilayer semiconductor structures*
The analysis of double-crystal x-ray rocking curves of single-crystal layered structures can give valuable information on layer strains, displacement of atoms from normal lattice sites (which reduces the structure factor), crystallographic misorientations, and crystal defects. Both strains and misorientations cause shifts in the Bragg angle. These two effects are readily separated using two or ...

متن کاملX-ray diffraction from microtubules.
X-ray diffraction patterns from sperm-tail microtubules indicate that subunits with a 40 to 50 A packing diameter form filaments, alternately half-staggered, parallel to the tubule axis. A 12-or a 13-stranded structure fits best with the X-ray diagram. The strongest bonding is that between units within a longitudinal filament; the weaker lateral interactions are disrupted by drying. Microtubule...
متن کاملApplication of X-ray Diffraction Techniques to the Semiconductor Field
generally arranged at a distance of 0.1 nm to 0.5 nm from one another. When such a substance is irradiated with X-rays having a wavelength roughly equivalent to the interatomic or intermolecular distance, the Xray diffraction phenomenon will take place. X-ray diffraction is widely used in the semiconductor field because it is nondestructive and yields crystal structure information relatively ea...
متن کاملX-ray diffraction from rectangular slits.
It is shown that for micrometre-sized beams the X-ray diffraction from slits is a source of strong parasitic background, even for slits of high quality. In order to illustrate this effect, the coherent diffraction from rectangular slits has been studied in detail. A large number of interference fringes with strong visibility have been observed using a single set of slits made of polished cylind...
