This material requires high-temperature vacuum evaporation for thin-film deposition. Performance depends on matching source hardware, liner material, and evaporation method to the material's melting point and Z-ratio.
- Evaporation Method Constraint: Use E-beam evaporation as the preferred method; thermal evaporation requires RFQ confirmation.
- Source Hardware Compatibility: Select an E-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat to avoid contamination.
- Melting Point Constraint: The material's melting point of approximately 2600°C dictates the power and thermal management requirements of the evaporation source.
- Z-Ratio for Deposition Control: The Z-ratio of 1.00 simplifies quartz crystal microbalance calibration but must be verified for thickness monitoring.
- Purity and Size Consistency: The 99.975% purity and 8-28 nm particle size ensure consistent evaporation behavior and film quality.
Why is e-beam evaporation preferred over thermal evaporation for CeO2 pieces, and under what conditions can thermal evaporation be used?
E-beam evaporation is preferred for this CeO2 material due to its high melting point (~2,600°C), which exceeds the practical range of most thermal boats. The source specifies e-beam evaporation as preferred, with thermal evaporation available only by RFQ. E-beam performance is rated as Good when using a graphite/Al2O3/BN liner or W/Mo/Ta boat. Thermal evaporation requires a custom quotation and is not recommended as a standard process.
What liner or boat materials are compatible with CeO2 evaporation to avoid contamination or crucible damage?
The recommended liner materials for e-beam hearth include graphite, Al2O3, or BN, while boats can be made from W, Mo, or Ta. The source also lists Sheet2 hardware options of Tantalum, Graphite, and W. These materials are selected to withstand the high melting point and resist chemical reaction with CeO2. Using incompatible materials may lead to contamination or crucible failure.
What is the significance of the Z-ratio of 1.00 for this CeO2 material in quartz crystal microbalance deposition monitoring?
The Z-ratio of 1.00 is listed as a default reference value for the CeO2 material. In quartz crystal microbalance monitoring, the Z-ratio corrects for the acoustic impedance difference between the deposited film and the crystal. A value of 1.00 is common for materials with acoustic properties similar to the quartz crystal, but actual CeO2 films may have a different Z-ratio; users should verify with the manufacturer or perform calibration runs. The source marks this value with double asterisks, indicating it is a supplied reference rather than a measured constant.
Cerium(IV)Oxide (CeO2) Evaporation Material, Pieces, 99.975%, 8-28 nm is a high-purity compound evaporation material optimized for E-beam deposition, with a melting point of ~2,600°C and density of 7.13 g/cm³, requiring specific liner or boat materials for thermal stability.
Positive
- High purity for film integrity: 99.975% purity minimizes contamination in thin-film deposition, supporting consistent optical or barrier properties in vacuum processes.
- Defined nanoscale particle size: Pieces sized 8-28 nm facilitate controlled evaporation rates and uniform source loading in E-beam systems, reducing process variability.
Trade-offs
- High melting point requires robust hardware: Melting point of ~2,600°C necessitates use of graphite, Al2O3, or BN liners in E-beam hearths, limiting compatibility with standard boats and increasing setup complexity.
- Thermal evaporation requires RFQ confirmation: Thermal evaporation is only supported by RFQ, indicating potential process constraints or reduced performance outside E-beam methods, requiring pre-order validation.
