|Screw dislocations can climb, too. As a result they turn into a helix; a real "screw". The segments finally may collapse into a system of coaxial dislocation loops.
|The images show screw dislocations in the emitter area of bipolar transistors in an early and advanced stadium of climb (right and center) and the final collapse into dislocation loops.
