Relative dislocation density using the approach of Hirsch et al.
Dislocation Density, ρ = (β2)/(9.b2)
b = Burgers Vector, and
β = Integrated Breadth (computed numerically from XRD profile data)
Let us take the example of SiC 4H (004)s reflection and the use of XRD rocking curve analysis.
How should I figure out b, Burgers Vector?
