Platinum-on-Silicon Substrate: A Clean Conductive Surface for AFM

Features

• Sputtered platinum film
• Titanium adhesion layer for a durable film that won’t flake
• Consistent surface roughness
• Platinum is chemically stable and resists oxidation, so the surface stays reliable between uses
• Diced to 8 mm × 8 mm, sized to fit standard AFM stubs and discs
  

Applications

• Conductive AFM: use as a uniform counter-electrode and a known good contact
• KPFM and EFM: serve as a stable metal reference surface for surface-potential measurements
• Tip checks: confirm a probe is still conductive before committing to a valuable sample
• Force spectroscopy: use as a clean, flat surface for adhesion and force-curve tests [confirm]
• Substrate: deposit nanoparticles, 2D materials, or molecules on a flat conductive support [confirm]
• Training: give new users a forgiving conductive sample
