This powder is designed for vacuum thin-film deposition via e-beam evaporation (preferred) or thermal evaporation by request. The material requires a compatible e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat, and must be matched to the deposition source geometry and process.
- Evaporation Source Compatibility: Load the powder into an e-beam hearth with a graphite, Al2O3, or BN liner, or into a refractory metal boat (W, Mo, or Ta) to avoid contamination and ensure proper evaporation.
- Particle Size Verification: Confirm the 13-47 nm particle size range to ensure uniform source loading and consistent evaporation rates during deposition.
- Melting Point Handling: Ensure sufficient e-beam power or thermal source capacity to reach the 2,350°C melting point for effective vaporization.
- Density Consideration: Account for the 8.35 g/cm³ density when calculating source charge volume and expected film thickness.
Why is E-beam evaporation preferred over thermal evaporation for Samarium Oxide (Sm2O3) powder with a melting point of 2,350°C?
E-beam evaporation is preferred for this Sm2O3 powder because the material's high melting point of 2,350°C and powder form make it well-suited for E-beam hearths, where performance is rated as 'Good'. Thermal evaporation is possible only by special request (RFQ), as the high melting point may exceed the capabilities of standard thermal boats without custom setup.
What liner or boat materials are compatible with evaporating Samarium Oxide (Sm2O3) powder in an E-beam system?
The specified compatible liner materials for E-beam evaporation of Sm2O3 powder are graphite, Al2O3, or BN liners, and the compatible boat materials are W, Mo, or Ta. These materials are recommended to avoid chemical reaction and ensure stable evaporation at the 2,350°C melting point.
Samarium Oxide (Sm2O3) evaporation material in 99.99% purity and 13-47 nm powder form is evaluated for E-beam evaporation with good performance using graphite/Al2O3/BN liners or W/Mo/Ta boats, requiring careful matching of deposition source hardware and process route due to its high melting point of 2,350 °C and density of 8.35 g/cm³.
Positive
- High purity and defined particle size: 99.99% purity and 13-47 nm powder size enable consistent film stoichiometry and controlled deposition rates for research-grade thin-film applications.
- Compatible with multiple evaporation sources: Supports E-beam evaporation with graphite/Al2O3/BN liners or W/Mo/Ta boats, offering flexibility in deposition hardware selection for different lab setups.
Trade-offs
- High melting point requires robust hardware: Melting point of 2,350 °C demands high-temperature evaporation sources and liners, increasing infrastructure requirements and operational complexity.
- Thermal evaporation requires RFQ confirmation: Thermal evaporation is only available by RFQ, limiting process flexibility and requiring additional lead time for alternative deposition methods.
