In-Situ Formation of a Grain Boundary in Field Ion Microscopy Using a Laser.

Abstract

Successful formation and real-time observation is reported of a grain boundary within a view of a FI image using laser beam irradiation in the presence of a high electric field. Formation of the grain boundary in a FI tip appears to be by solid-phase recrystallization due to moderate local heating and extremely high mechanical stresses caused by the electric field and laser irradiation.
