- Diffraction conditions are fulfilled on the perimeter of the Laue circle.
- Some inelastically scattered electrons penetrate the bulk crystal and fulfill Bragg diffraction conditions.
- However, non-flat surfaces add additional diffraction conditions to RHEED analysis.
- Diffraction conditions are satisfied where the rods of reciprocal lattice intersect the Ewald's sphere.
- Figure 3 shows a cross sectional view of a single row of reciprocal lattice rods filling of the diffraction conditions.
- These inelastically scattered electrons can reach the detector to yield kikuchi diffraction patterns, which are useful for calculating diffraction conditions.
- The intensity never shrinks to zero even far from diffraction conditions, however, due to incoherent elastic scattering from surface defects.
- The melting temperature is estimated from the beam intensity, while changes in the diffraction conditions to indicate phase transition from solid to liquid.
- The k vector, corresponds to an allowed diffraction condition, and the G vector is the difference between the k and k 0 vectors.
- Growing films, nucleating particles, crystal twinning, grains of varying size and adsorbed species add complicated diffraction conditions to those of a perfect surface.
- It's difficult to see diffraction condition in a sentence. 用diffraction condition造句挺難的
- Diffraction conditions are fulfilled over the entire intersection of the rods with the sphere, yielding elongated points or streaks along the vertical axis of the RHEED pattern.
- Many of the reciprocal lattice rods meet the diffraction condition, however the RHEED system is designed such that only the low orders of diffraction are incident on the detector.
- However, only the first few layers of the material contribute to the diffraction in RHEED, so there are no diffraction conditions in the dimension perpendicular to the sample surface.
- The reciprocal lattice points are the values of momentum transfer where the Bragg diffraction condition is satisfied and for diffraction to occur the scattering vector must be equal to a reciprocal lattice vector.
- The intrinsic width of a Bragg reflection, as calculated by dynamical diffraction theory, is extremely small ( on the order of 0.001?under conventional X-ray diffraction conditions ).
- The utmost care must be taken to record such ED patterns from the thinnest areas in order to keep most of the structure related intensity differences between the reflections ( quasi-kinematical diffraction conditions ).
- Modern TEMs are often equipped with specimen holders that allow the user to tilt the specimen to a range of angles in order to obtain specific diffraction conditions, and apertures placed above the specimen allow the user to select electrons that would otherwise be diffracted in a particular direction from entering the specimen.
