TEM Window Example - Single Crystalarrow12Pure Silicon TEM Windows

Pure Silicon set these TEM Windows apart from the rest

TEM Window dimensions are 2.9mm in diameter and 100µm thick.

Features

  • Nanometer Thinness - Pure Silicon TEM Windows feature imaging windows with 5 to 15 nm thickness, reducing background contribution and interference for higher contrast imaging. Most impressively, 5 nm thick Non-Porous Pure Silicon TEM Windows are thinner than the thinnest commercially available amorphous carbon membranes.
  • Plasma Cleanable - can be vigorously plasma cleaned to remove organic contamination, unlike traditional carbon grids
  • Field to Field Uniformity - Non-Porous Pure Silicon TEM Windows are more consistently thin than carbon grids, reducing field-to-field variability. (Note: Porous windows do have inherent crystalline features, but feature background-free nanometer-scale pores).
  • Reduced Chromatic BlurReduced Chromatic Blur - In comparison to the thinnest commercially available amorphous carbon membranes, 5 nm Non-Porous Pure Silicon TEM Windows yield half the chromatic blur. This dramatic difference results from a two-fold reduction in inelastic scattering of electrons passing through the thinner membranes of Silicon TEM Windows. In turn, the reduced chromatic blur offers a potential two-fold improvement in imaging resolution.
  • Nanometer-Scale PoresNanometer-Scale Pores - Pure Silicon TEM Windows are available as porous films with pores ranging from 5 to 50 nm in diameter. The pores allow simple and stable suspension of nanoscale materials for imaging without intervening background.
  • Silicon Composition - The elemental silicon composition of TEM Windows remarkably increases stability at high beam currents and at high annealing temperatures. The Pure Silicon composition also introduces a minimal background signal, making elemental analyses of sample containing nitrogen and/or carbon possible by EDX and EELS.
  • Isolated Poly-CrystallinityIsolated Poly-Crystallinity - The poly-crystalline nature of porous Pure Silicon TEM Windows offers an internal calibration standard for x-ray diffraction studies. The isolated crystalline features also provides a convenient and reliable scale for high-resolution size measurements, well-characterized crystal lattice of silicon.
  • Hydrophilicity - The hydrophilicity of both non-porous and porous Pure Silicon TEM Windows is tunable by plasma and/or ozone treatment making sample preparation easier, particularly for samples in aqueous solutions.
  • Increased Stability - At high beam currents and high annealing temperatures (600°C for non-porous, >1000°C for nanoporous)
  • Silicon Composition - Sputter-deposited, pure, intrinsic silicon
  • Minimal Background Signal - Enables elemental analyses of samples containing nitrogen and/or carbon

Options

  • Nanoporous - Using P30 membranes has made the Nanoporous TEM windows significantly more porous. Pore sizes have increased to include a range of pores from 10-60 nanometers in diameter.
  • Single Crystal - with <1-0-0> orientation, offers a very thin 35nm membranes for diffraction studies and other applications requiring uniform background from a single crystal film.
  • Non-porous - Non-Porous films are lightly wrinkled with approximately 5 microns or less deflection across 100 microns of travel. This is typically not problematic for high-resolution imaging.
