This material requires e-beam evaporation as the preferred deposition method, with thermal evaporation available only by RFQ. Deposition source hardware must be matched to the material's melting point and evaporation behavior for acceptable performance.
- Source Compatibility: Use e-beam hearth with graphite, Al2O3, or BN liner, or W/Mo/Ta boat for evaporation.
- Performance Note: E-beam evaporation performance with this material is rated as Fair.
- Process Matching: Confirm that the evaporation source hardware and process route are compatible with the material's melting point and film requirements.
What is the Z-ratio of 0.556 for ZnO evaporation material and how does it affect quartz crystal microbalance (QCM) thickness monitoring accuracy?
The Z-ratio of 0.556 is a material-specific acoustic impedance factor used to correct QCM thickness readings. For ZnO, this value indicates a moderate deviation from the default quartz crystal calibration, requiring tooling factor adjustment to maintain deposition rate accuracy. Users should enter this Z-ratio into their deposition controller to avoid film thickness errors.
Which liner or boat materials are compatible with E-beam evaporation of ZnO pieces to avoid chemical reaction or contamination?
For E-beam evaporation of ZnO, compatible lining materials include graphite, alumina (Al2O3), and boron nitride (BN) for crucible liners, or tungsten (W), molybdenum (Mo), and tantalum (Ta) boats. The product specification explicitly recommends these materials to prevent chemical interaction with the molten ZnO at its melting point of 1,975°C. Using an incompatible liner could introduce impurities or degrade the evaporation source.
Given the melting point of 1,975°C, what infrastructure considerations are required for evaporating ZnO pieces in a laboratory vacuum system?
The high melting point of 1,975°C for ZnO necessitates a high-temperature E-beam evaporation source. The product indicates E-beam evaporation is preferred, with thermal evaporation available only by RFQ. The system must be equipped with a water-cooled hearth and appropriate liners (graphite, Al2O3, BN, or refractory metal boats) to withstand the thermal load. Additionally, the density of 5.61 g/cm³ and piece form factor of 3 mm should be considered for source loading and thermal contact.
Zinc Oxide (ZnO) evaporation material in 3 mm pieces at 99.9% purity is evaluated for e-beam evaporation with fair performance, requiring graphite/Al2O3/BN liners or W/Mo/Ta boats, and thermal evaporation by RFQ only, with a high melting point of 1,975 °C and density of 5.61 g/cm³.
Positive
- Defined purity and form: 99.9% purity and 3 mm pieces enable consistent source loading and deposition process matching for research-grade thin-film workflows.
- Multiple pack size options: Available in 100 g, 500 g, and 1 kg packs, allowing flexible procurement scaling for laboratory R&D or pilot production without over-ordering.
Trade-offs
- E-beam performance rated fair: E-beam evaporation performance is rated as fair, indicating potential deposition rate instability or material utilization inefficiency that may require process optimization.
- Thermal evaporation requires RFQ: Thermal evaporation is not standard and requires a request for quotation, adding lead time and limiting direct process flexibility for labs without e-beam capability.
