Why Choose Ultra-flat Gold?

  • Ultra-Flat Surface: Gold surface roughness approaches atomic flatness and enables high-resolution imaging and measurements at the nanoscale.
  • Highly Oriented Gold: Uniform Au(111) domains through the entire area of the sample.
  • Pure & Uncontaminated Gold: Our gold is shielded from the atmosphere until stripped from the template, ensuring a surface free from organics and atmospheric contaminants.
  • Ready-to-Use: Say goodbye to the need for hazardous cleaning solutions or expensive equipment. Our chips are prepared for immediate use.
  • Convenience at Its Best: With multiple chips per template, prepare fresh, clean, and ultra-flat chips in seconds before your next experiment.

Product Details – Template-Stripped Gold Chips

Designed for researchers, these chips are fabricated by coating the finest prime grade silicon wafers as templates. Then, 1-cm x 1-cm square glass chips are epoxy-glued to the surface of the gold.  The gold surface you use is the one in contact with the silicon, so it is ultra-flat, highly-oriented Au(111), and protected from the atmosphere until you are ready to use it.

Immediately upon stripping, Template Stripped Gold Chips provide an RMS roughness approaching atomic flatness, with a water static contact angle substantially similar to that of a freshly-deposited, high-energy gold surface.

Analysis of Ultra-flat gold(111)

Scanning tunneling microscopy: High-resolution STM images of ultra-flat gold surfaces demonstrate large grains of gold with uniform surface roughness over the entire area analyzed.

Electron backscatter diffraction: Crystallography studies demonstrate ultra-flat gold films have a uniform Au(111) orientation that covers the entire area of the sample.
