This material requires thermal evaporation or low-power electron-beam deposition using compatible crucible or boat materials. E-beam performance is fair, and the high melting point of 1,750°C demands careful source matching to avoid contamination or incomplete evaporation.
- Crucible and Boat Compatibility: Use quartz, alumina, or graphite crucibles, or tantalum/tungsten boats, or Knudsen cells for thermal evaporation.
- E-Beam Performance Limitation: Electron-beam evaporation is only fair for CdS, and low-power operation is recommended to avoid material degradation.
- Melting Point Requirement: The melting point of 1,750°C requires source materials capable of sustained high-temperature operation without reaction.
- Particle Size and Loading: The 1-3 mm piece size is suitable for direct loading into crucibles or boats without additional crushing.
- Z-Ratio for Deposition Control: The Z-ratio of 1.02 indicates minimal acoustic impedance mismatch, simplifying quartz crystal monitor calibration during deposition.
Why is the e-beam performance rated as 'Fair' for this CdS evaporation material, and which deposition method is recommended?
The e-beam performance is rated as 'Fair' for this CdS evaporation material, indicating it is not optimal for high-power e-beam deposition. Thermal evaporation or low-power e-beam is recommended, with suitability confirmed by RFQ. The material is compatible with Quartz, alumina, or graphite crucibles, Ta/W boats, or Knudsen cells for thermal evaporation.
What crucible and boat materials are compatible with this CdS evaporation material for thermal deposition?
This CdS evaporation material is compatible with Quartz, alumina, and graphite crucibles, as well as Ta/W boats and Knudsen cells, with specific hardware selection confirmed by RFQ. The product description also lists W, Mo, Ta, and Al2O3 as compatible crucible or boat materials for thermal evaporation.
What is the physical form and particle size of this CdS evaporation material, and how does it affect handling in vacuum deposition?
The material is supplied as Pieces with a size range of 1–3 mm and a purity of 99.99%. The piece form and narrow size range facilitate consistent source loading and controlled evaporation in thermal or low-power e-beam processes, and the pack sizes available (25g, 100g, 500g, 1kg) allow selection based on deposition run requirements.
Technical evaluation of Atomfair Cadmium Sulfide (CdS) Evaporation Material, Pieces, 99.99%, 1-3 mm: high-purity compound suitable for thermal evaporation or low-power e-beam deposition, with defined particle size (1-3 mm) for consistent source loading. However, e-beam performance is rated as 'Fair' and requires specific crucible materials (quartz, alumina, graphite) and boat configurations (Ta, W) for optimal use.
Positive
- High purity 99.99%: Material purity is specified at 99.99%, enabling reproducible thin-film composition and reduced contamination in vacuum deposition processes.
- Defined particle size 1–3 mm: Supplied as pieces in a controlled 1–3 mm size range, which supports consistent source loading and stable evaporation rates during thermal or e-beam deposition.
Trade-offs
- Fair e-beam performance: E-beam evaporation is rated as 'Fair' per the datasheet, indicating potential limitations for high-rate or thick-film deposition compared to other materials.
- Crucible and boat constraints: Optimal evaporation requires specific crucible and boat materials (quartz, alumina, graphite, Ta, W) and some methods require RFQ confirmation, adding procurement coordination.
