Sample Preparation Variables

  • Angle lapping
  • Ball cratering
  • Blisters – break open with tweezers
  • Carbon is often deposited by SEM
  • Chemical derivatization
  • Chemical etch
  • Clean sample mount
  • Clean with gas jet
  • Clean with solvents
  • Cleanliness
  • Contamination
  • Damage can be caused by SEM
  • Doping: n-, p- vs none
  • Floating or grounded
  • Fracture (in air, in LN2, under solvent)
  • Glove bag (argon fill)
