Dislocation density 

Thanks for the video. However, can you perform an example that shows the determination of dislocation density from the TEM image? Thanks!

Sir, how to measure total length of dislocation?

sir please let me know that how to find TDD of a sample i.e 2*109cm-2

nice

Ye real me step surface dikhta h kya?

Sir in a crystal, length of dislocations could be different for different dislocations if we consider that they can end in a node(where disslocations are intersecting), so in that case will dislocation density be different for each dislocation ? or we always consider dislocation length to be equal to length of edge of crystal?

Sir in some books it is written as 10 ^-6 in case of dislocation density is it correct
