Peierls-Nabarro barrier

    I can not find what is exactly Peierls-Nabarro barrier? Could you gave me some explanation or reference. Everything I found are just different papers which I can not understand.

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    It's the stress required to make a dislocation glide in an otherwise perfect lattice. Try Introduction to Dislocations by Hull and Bacon. It should be in any introductory treatment of dislocations.
