AFM METAL SPECIMEN DISCS, GOLD-COATED, WITH CARRIER BOX
Advanced nanotechnology specimen support.
Gold-coated AFM discs provide excellent substrates for mounting specimens, due to their high resistance to electromigration, high electrical and thermal conductivity and high temperature operation properties. Gold is the most inert metal. Its adhesion to polymers is expected to be lower than that of other metals, however polymer irradiation with UV light and plasma discharge have been reported to enhance metal-polymer adhesion.

SILICON WAFERS CUT INTO CHIPS
Specimen support for SEM, SIMS, AFM.

These may be used for mounting very fine particulate matter. They are chemically inert and make good substrates for growing or mounting cells.
They are also useful when this smooth, inert background is required and for the determination of resolution and contrast of "in-the-lens" SEMs equipped with high brightness electron emitters. Additionally, conducting specimens, or non-conducting specimens in low vacuum or low voltage SEM, may be viewed without coating.
Si chips are opaque, have low electrical resistance, are very smooth, brittle and hard like glass. Si chips are chemically quite inert. These chips are pre-cleaned, but for tissue and cell culture, additional cleaning and sterilising may be required.
Unlike glass, Si chips are crystalline and they are cut on the >111< orientation.

The wafers are cut into chips measuring 5 x 5mm, 5 x 7mm or 10 x 10mm.

Properties
Orientation (111)
Resistance 1-30 Ohms
Type P (Boron) if 1 primary flat Type N (Phosphor) if also a secondary flat, 45 degrees from primary flat, is present
No SiO2 top coating
Wafer thickness is 460 - 530µm
Wafer is polished on one side
After dicing they are rinsed in DI water for cleaning

SILICON NITRIDE COATED DISCS, Ø 3MM
These 3mm silicon discs have a 50µm ultra low stress silicon nitride layer (Si3N4) on both sides and can be used as specimen discs for AFM applications, which need a Si3N4 background. The disks are made with the same state-of-the-art manufacturing techniques as the PELCO® silicon nitride support films. The disk are perfectly round and have the Easygrip™ edge for easy handling. Clean surface, no broken edges and free of debris often associated with other manufacturing processes. The ultra-low-stress film is nonstoichiometric and closer to SiN than Si3N4.

Specifications
Film thickness: 50nm ultra low stress Si₃N₄ on both sides
Disc thickness: 200µm silicon support
Disc diameter: 3mm
Surface roughness: The RMS (Rq) is 0.65 +/- 0.06nm which gives a mean roughness (Ra) of 0.45 +/- 0.02nm
Packaging: The PELCO® Silicon aperture frames are packaged under cleanroom conditions in the PELCO^® TEM Grid Storage box. Each box holds 10 discs.
