Deposition-source compatibility must be matched to the material's melting point (1356°C) and Z-ratio (0.66) to ensure proper evaporation. The pellets must be loaded into a Ta/W boat, Ta liner, or water-cooled e-beam hearth within a compatible vacuum system.
- Evaporation Method Compatibility: E-beam or thermal/resistive evaporation must be selected by RFQ to match source hardware to the material's melting point and Z-ratio.
- Source Hardware Requirements: The evaporation source must be a Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner to contain the pellets during deposition.
- Pellet Size Constraint: The 1-10 mm pellet size must be confirmed compatible with the source loading geometry and feed mechanism.
- Purity Verification: The 99.99% purity specification should be verified by certificate analysis before use in sensitive thin-film applications.
What is the Z-ratio of 0.66 for Terbium pellets and how does it affect deposition rate monitoring during e-beam evaporation?
The Z-ratio of 0.66 is a material-specific parameter used in quartz crystal microbalance (QCM) monitoring to correct for acoustic impedance mismatch between the deposited film and the crystal sensor. This value must be entered into the deposition controller's tooling factor settings to ensure accurate thickness measurement and rate control during e-beam evaporation of Terbium.
What evaporation source materials are compatible with Terbium pellets to avoid contamination during thermal or e-beam deposition?
The product is designed for use with Ta/W boats, Ta liners, or water-cooled e-beam hearths with liner. These materials are selected to withstand the 1,356°C melting point of Terbium without significant alloying or reactivity. RFQ confirmation of source compatibility is required for specific process conditions.
What safety documentation and handling precautions are available for Terbium evaporation material?
The product includes a certificate of analysis and a safety data sheet (SDS) that can be reviewed for handling, storage, and shipping conditions. Users should confirm the SDS aligns with their laboratory safety protocols before use, as the material is a research-grade rare earth metal with a high melting point of 1,356°C.
Atomfair Terbium pellets (99.99%, 1–10 mm) are a research-grade evaporation material offering high purity for advanced thin-film deposition, but require careful process control due to its high melting point (1,356°C) and non-unity Z-ratio (0.66).
Positive
- High purity 99.99% for deposition: The 99.99% purity minimizes contaminant incorporation in thin films, critical for applications in magneto-optical devices and spintronics.
- Pellet form with defined size range: The 1–10 mm pellet size facilitates consistent source loading and controlled evaporation rate in both e-beam and thermal boats.
Trade-offs
- High melting point 1,356°C: Evaporation requires high-temperature source hardware (e.g., Ta/W boat, e-beam hearth) and precise power control to avoid thermal damage to the source.
- Z-ratio 0.66 requires calibrated monitoring: The non-unity Z-ratio necessitates accurate crystal sensor calibration for reliable film thickness control during deposition.
