This material requires vacuum deposition equipment with compatible source hardware such as Ta/W boats, Ta liners, or water-cooled e-beam hearths. The melting point of 1529°C and Z-ratio of 0.74 must be factored into process parameter selection and quartz crystal monitor calibration.
- Deposition Source Compatibility: Confirm compatibility with Ta/W boat, Ta liner, or water-cooled e-beam hearth configurations before use.
- Evaporation Method Selection: Select e-beam or thermal/resistive evaporation based on material behavior and film requirements, confirmed via RFQ.
- Process Parameter Integration: Incorporate melting point (1529°C) and Z-ratio (0.74) into deposition rate and thickness monitoring calibration.
- Pre-Use Validation: Confirm material purity, form, size range, and pack size against deposition source geometry before use.
What are the critical parameters to consider when selecting Erbium evaporation pellets for e-beam versus thermal evaporation?
The choice depends on the melting point (1,529°C), density (9.07 g/cm³), and Z-ratio (0.74). For e-beam evaporation, a water-cooled e-beam hearth with liner is recommended; for thermal/resistive evaporation, a Ta/W boat or Ta liner is suitable. The pellets are offered in a 1-10 mm size range, compatible with both methods.
What evaporation source materials are compatible with these Erbium pellets?
The product is compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner. The source material must be selected based on the evaporation method (e-beam or thermal/resistive) and the melting point of Erbium (1,529°C). Buyers should confirm source geometry and deposition hardware before quotation.
What documentation and safety considerations are required for laboratory procurement of Erbium evaporation material?
Buyers should review the certificate of analysis, safety data sheet, shipment conditions, and export requirements. The product is 99.99% pure Erbium in pellet form, 1-10 mm, and requires proper handling as a research-grade material. Contact the supplier for specific safety data and documentation review against laboratory use requirements.
Erbium (Er) evaporation pellets at 99.99% purity and 1-10 mm pellet size are suited for vacuum thin-film deposition, but require compatible evaporation source hardware (e.g., Ta/W boat, Ta liner, or water-cooled e-beam hearth) due to the high melting point of 1529°C, and users must account for a Z-ratio of 0.74 in quartz crystal monitor settings for accurate film thickness control.
Positive
- High purity 99.99%: The 99.99% purity specification reduces contaminant incorporation in deposited thin films, which is critical for applications requiring precise stoichiometry or low defect density in optical or electronic coatings.
- Defined pellet size 1-10 mm: The specified pellet size range of 1-10 mm facilitates consistent loading into evaporation sources (boats, liners, or e-beam hearths), promoting uniform evaporation rates and reducing source clogging or spitting.
Trade-offs
- High melting point 1529°C: The melting point of 1529°C requires robust evaporation source hardware such as Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners; standard tungsten boats may degrade rapidly, necessitating RFQ for compatible source materials.
- Z-ratio 0.74 for thickness monitoring: The Z-ratio of 0.74 must be programmed into quartz crystal microbalance controllers to accurately measure film thickness; incorrect setting leads to systematic errors in deposition rate control and final film thickness.
