This material requires careful matching to evaporation source hardware and method. Process parameters must be calibrated based on the material's melting point and Z-ratio for consistent thin-film deposition.
- Evaporation Source Compatibility: Use only Mo/W/Ta boat or graphite/alumina crucible to avoid contamination and ensure proper evaporation.
- Evaporation Method: Thermal/resistive evaporation is preferred; low-power e-beam may be used with caution.
- Process Parameter Calibration: Calibrate deposition rate and thickness monitoring using the material's melting point of 420°C and Z-ratio of 0.514.
- Material Form Handling: The 1–3 mm pellet form allows direct loading into evaporation sources without additional processing.
- Purity Requirements: Maintain 99.99% purity by avoiding cross-contamination during handling and storage.
What is the recommended evaporation source for zinc pellets with 99.99% purity and 1-3 mm size?
Thermal/resistive evaporation is preferred. Low-power e-beam is optional using a Mo/W/Ta boat or graphite/alumina crucible, as specified in the product documentation for this zinc evaporation material.
What does the Z-ratio of 0.514 indicate for process control when depositing zinc films from these pellets?
The Z-ratio of 0.514 is used in quartz crystal microbalance (QCM) monitoring to correct for the acoustic impedance mismatch between the deposited zinc and the crystal sensor, ensuring accurate film thickness measurement during thermal or e-beam evaporation. This value is specific to the material's density of 7.14 g/cm³.
What is the melting point of these zinc evaporation pellets and how does it affect deposition system requirements?
The melting point is 420°C, which is relatively low compared to many evaporation materials. This allows efficient thermal evaporation at moderate temperatures, reducing the risk of crucible contamination and enabling use with standard refractory metal boats or alumina crucibles as noted in the product specifications.
Zinc (Zn) evaporation material in pellet form with 99.99% purity and 1-3 mm size is suitable for thermal/resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles, requiring careful process parameter matching due to its melting point of 420°C and Z-ratio of 0.514.
Positive
- High purity 99.99% zinc pellets: Material specification of 99.99% purity ensures consistent thin-film deposition with minimal contamination for research-grade applications.
- Optimized pellet form for loading: Pellets sized 1-3 mm facilitate uniform source loading and controlled evaporation in thermal/resistive or low-power e-beam systems.
Trade-offs
- Specific evaporation hardware required: Deposition requires Mo/W/Ta boat or graphite/alumina crucible; thermal/resistive method preferred, limiting compatibility with alternative e-beam setups.
- Process parameter sensitivity: Melting point of 420°C and Z-ratio of 0.514 necessitate careful calibration of deposition parameters to achieve target film thickness and stoichiometry.
