71893-12arrow11Silicon Chip Specimen Supports

Super-smooth polished silicon.

These mounts are perfect for applications where the surfaces of carbon or aluminum stubs may cause interference. They have surface properties equal to glass, are opaque, and possess low electrical resistance.

Applications

  • Examining small particles with fine structure.
  • Mounting cell structures.
  • Determining contrast and resolution of "in-the-lens" field emission SEMs.

All chips are packaged clean and polished on one side. Attach to any type of specimen stub. Each chip is pre-cut from a 4" (10 cm) wafer.

Available sizes: 3 x 3 mm, 5 x 5 mm, 5 x 7 mm, 10 x 10 mm, 20 x 20 mm, 20 x 30 mm.

Specifications

Surface Roughness: less than 1nm
Crystallographic Orientation: (100)
Resistance: 1-30 Ohms
Type: P(Boron)(1 primary flat)
Wafer Thickness: 460-530 µm
SiO2 Top Coat: None

arrow11Single Crystal Substrates

High purity, optical-grade NaCl, KBr and KCl.
  • Ideal for education, thin film research, and single crystal film research
  • Excellent substrates for growing epitaxial films
  • Less than 1% impurity

Orientation of vacuum-coated thin films is directly related to the orientation of the single-crystal substrate used to create single-crystal films. For most applications, freshly cleaved substrates are recommended. cleaved crystal surfaces produce atomically flat areas, but some cleavage stepping over different atomic planes is to be expected.

Sodium chloride (NaCl), potassium bromide (KBr), and potassium chloride (KCl) crystals are available. Crystal size is 10 x 10 x 10 mm with (100) orientation. Supplied in packs of 5.
