Gadolinium evaporation material requires precise matching of source hardware and process parameters to achieve consistent film deposition. The material's melting point, density, and Z-ratio dictate boat or hearth liner compatibility and thermal management during evaporation.
- Source Hardware Compatibility: Use only Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner to avoid material contamination or inadequate evaporation.
- Evaporation Method Selection: Select E-beam or thermal/resistive evaporation based on the material's melting point and required film properties, and confirm via RFQ.
- Thermal Management: Account for the melting point of 1,313°C and density of 7.9 g/cm³ when setting power levels and cooling rates to prevent splattering or incomplete evaporation.
- Film Thickness Calibration: Use the Z-ratio of 0.67 to calibrate quartz crystal microbalance for accurate film thickness measurement during deposition.
What is the Z-ratio of Gadolinium (Gd) evaporation material and how does it affect deposition rate monitoring?
The Z-ratio is 0.67. This value is used in quartz crystal microbalance (QCM) calibration to correct for the acoustic impedance of Gd, enabling accurate film thickness and deposition rate control during vacuum thin-film processes.
What boat or liner materials are compatible with Gadolinium evaporation for thermal or E-beam deposition?
Gadolinium can be evaporated using Ta/W boats, Ta liners, or water-cooled E-beam hearths with liner. The specific choice depends on the evaporation method (thermal/resistive vs. E-beam) and must be confirmed via RFQ to ensure proper wetting and avoid contamination.
What is the melting point of Gadolinium evaporation material and what are the implications for deposition system requirements?
The melting point of Gadolinium is 1313°C. This relatively high melting point requires a suitable evaporation source such as E-beam or thermal with refractory boat materials, and the system must be capable of reaching and maintaining the required temperature without degrading the source.
Gadolinium (Gd) evaporation material in pieces (1-10 mm) with 99.99% purity, suitable for e-beam or thermal evaporation. Requires careful source matching and deposition rate calibration due to its melting point of 1,313°C and Z-Ratio of 0.67.
Positive
- High-purity 99.99% material: The 99.99% purity specification minimizes contamination risks in thin-film deposition, supporting reproducible film properties for research or device fabrication.
- Flexible evaporation source compatibility: Supports both e-beam and thermal/resistive evaporation using Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners, allowing integration into diverse deposition systems.
Trade-offs
- High melting point requires specialized sources: The melting point of 1,313°C necessitates use of high-temperature evaporation sources (e.g., Ta/W boats or water-cooled e-beam hearths) and may not be compatible with standard thermal boats without verification.
- Z-Ratio must be calibrated for accurate thickness monitoring: The specified Z-Ratio of 0.67 must be programmed into quartz crystal microbalance controllers to avoid systematic errors in deposited film thickness during evaporation.
