Terbium evaporation pellets require a compatible evaporation source such as Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner. The material's melting point of 1356 °C and Z-ratio of 0.66 must be accounted for during deposition process calibration.
- Source Compatibility: Use only Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner as the evaporation source.
- Temperature Requirement: The evaporation source must reach at least 1356 °C to melt the terbium pellets.
- Thickness Monitor Calibration: Enter the Z-ratio of 0.66 into the quartz crystal monitor for accurate film thickness measurement.
- Process Route Matching: Select the evaporation method (e-beam or thermal/resistive) based on the material's behavior and desired film properties.
How does the Z-Ratio of 0.66 for Tb evaporation material influence the accuracy of thin-film thickness monitoring using a quartz crystal microbalance?
The Z-Ratio of 0.66 is a material-specific acoustic impedance factor that must be programmed into the deposition controller. It corrects the QCM reading to account for the elastic properties of Tb, preventing thickness errors. This value is critical for achieving the desired film thickness in e-beam or thermal evaporation processes.
What evaporation source configurations are compatible with Tb pellets for thermal and e-beam evaporation?
Tb pellets can be evaporated using a Ta/W boat, a Ta liner, or a water-cooled e-beam hearth with liner. These configurations are specified to withstand the 1,356°C melting point and ensure uniform deposition. The exact choice depends on the evaporation method and should be confirmed via RFQ.
What procurement documentation and conditions should be reviewed before ordering Tb evaporation material for laboratory use?
Buyers must verify the certificate of analysis, safety data sheet, shipment conditions, and export requirements. The product requires confirmation of model, purity (99.9%), form (pellets 1-10 mm), pack size, and deposition-source compatibility. These steps ensure the material meets laboratory-use requirements and avoids delays.
Atomfair Terbium evaporation pellets (99.9% purity, 1-10 mm) provide a defined material form for E-beam or thermal evaporation, with a melting point of 1,356°C and Z-ratio of 0.66 requiring careful source and calibration setup.
Positive
- Defined pellet form and size range: Supplied as pellets 1-10 mm, enabling consistent source loading and uniform evaporation rates in both boat and e-beam configurations.
- High purity for reproducible films: 99.9% purity specification supports standard research-grade thin-film deposition with minimal contamination from trace elements.
Trade-offs
- High melting point requires compatible hardware: Melting point of 1,356°C necessitates use of refractory metal boats (Ta/W) or water-cooled e-beam hearth to avoid thermal damage or alloying during evaporation.
- Z-ratio must be calibrated for thickness control: A Z-ratio of 0.66 must be entered into quartz crystal microbalance controllers to ensure accurate deposition rate and film thickness monitoring.
