Abstract in brief

  • The study uses Bragg coherent X-ray diffraction imaging to analyze how gold microcrystals recover from damage caused by focused ion beam (FIB) techniques during annealing, showing that multiple reflections help track changes accurately.
  • Findings indicate that FIB-induced strains in gold microcrystals can be mostly eliminated by heating them to 380-410°C, with the process involving diffusion of gallium below 280°C and gold self-diffusion above that temperature.
  • The research highlights that local temperature measurements via lattice expansion are more reliable than thermocouple readings due to thermal resistance, and analyzing strain and morphology evolution reveals the importance of measuring multiple crystal reflections for understanding material behavior.
