Ytterbium evaporation pellets require a high-vacuum environment and deposition source hardware compatible with the material's melting point and evaporation behavior. The process route must be matched to the specific boat or liner material and the e-beam or thermal evaporation method.
- Evaporation Source Hardware: Use Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner for Yb evaporation.
- Evaporation Method: Select e-beam or thermal/resistive evaporation based on process requirements.
- Melting Point Parameter: The material's melting point of 819°C must be factored into the evaporation rate and power settings.
- Z-Ratio Calibration: Use the Z-ratio of 1.13 for quartz crystal monitor thickness calibration during deposition.
- Vacuum Environment Requirement: Perform deposition under high vacuum to ensure film purity and consistent evaporation.
Why is the Z-ratio of 1.13 important when using Ytterbium evaporation material in quartz crystal microbalance (QCM) monitoring?
The Z-ratio of 1.13 is a material-specific correction factor required for accurate thin-film thickness measurement with QCM sensors. This value must be entered into the deposition controller to compensate for acoustic impedance mismatch between Yb and the quartz crystal. The product specification explicitly lists the Z-ratio as 1.13, which is essential for obtaining reliable rate and thickness data during e-beam or thermal evaporation.
Which evaporation source materials are compatible with Ytterbium pellets given its melting point of 819°C?
Ytterbium pellets are compatible with Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners. The product description specifies these as suitable evaporation sources for both e-beam and thermal/resistive evaporation, ensuring that the material does not react with the source at its melting point of 819°C. Buyers should confirm source geometry and liner compatibility before quotation.
How does the pellet size range of 1–10 mm influence loading and evaporation performance?
The 1–10 mm pellet size is designed to facilitate efficient loading into evaporation boats, crucibles, or e-beam hearths. This size range supports uniform feeding and consistent evaporation rates, as the product description states that the sizing aids source loading and evaporation review. The specific form factor is critical for maintaining stable deposition conditions in research-scale thin-film workflows.
Ytterbium (Yb) evaporation pellets at 99.9% purity with 1-10 mm pellet size are suitable for e-beam and thermal evaporation, requiring specific source liners (Ta/W, Ta) and careful process control due to their moderate melting point and density.
Positive
- 99.9% purity for reproducible deposition: The 99.9% purity specification enables consistent film composition and allows grade comparison for application-specific requirements.
- Pellet form with defined size range: Pellets sized 1-10 mm facilitate uniform source loading and compatibility with standard e-beam hearths and thermal boats.
Trade-offs
- Restricted evaporation source compatibility: This material requires Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner; other source materials may cause contamination or poor evaporation behavior.
- Moderate melting point and density: With a melting point of 819°C and density of 6.96 g/cm³, process parameters must be adjusted to avoid spitting or incomplete evaporation, particularly in thermal evaporation systems.
