This material is intended for vacuum thin-film deposition and requires specific evaporation source hardware and process validation. Pre-quotation confirmation of material purity, form, size, pack size, and deposition-source compatibility is mandatory.
- Evaporation Source Compatibility: Confirm that the hearth liner or boat material (graphite, Al2O3, BN, W, Mo, or Ta) is compatible with NiO at the melting point of 1984°C.
- Process Route Selection: Select E-beam evaporation as the preferred method; thermal evaporation requires RFQ and appropriate boat material selection.
- Pellets Handling: Load the 325 mesh pellets carefully to avoid contamination and ensure uniform evaporation during deposition.
What is the significance of the Z-ratio of 1.00 for Nickel Oxide evaporation material in quartz crystal microbalance (QCM) thin-film monitoring?
A Z-ratio of 1.00 indicates that NiO has the same acoustic impedance as the quartz crystal, so no tooling factor correction is needed for accurate film thickness monitoring with a QCM. This simplifies process setup and reduces calibration effort for researchers using this specific NiO evaporation material.
Which evaporation source liner or boat materials are compatible with NiO pellets to avoid chemical reaction or contamination during e-beam or thermal evaporation?
For e-beam evaporation, NiO pellets are compatible with graphite, Al2O3, or BN liners. For thermal evaporation by RFQ, W, Mo, or Ta boats are suitable, with Al2O3 additionally listed for sheet2 hardware configurations. This ensures material compatibility and minimizes contamination risks during deposition.
Why is e-beam evaporation the preferred method for NiO pellets with a melting point of 1984°C, and under what conditions can thermal evaporation be considered?
E-beam evaporation is preferred because the high melting point of 1984°C for NiO requires the high energy density of an electron beam to achieve efficient evaporation without degradation. Thermal evaporation may be considered but requires a formal RFQ process due to the need for compatible boat materials and higher thermal power handling.
Atomfair's Nickel Oxide (NiO) evaporation pellets (99.995%, 325 mesh) offer high purity and defined particle form for e-beam or thermal evaporation, but require compatible source hardware and controlled thermal processing due to the material's high melting point (1984°C) and density (6.67 g/cm³).
Positive
- High purity 99.995% for reliable film properties: The 99.995% purity specification minimizes contamination in thin-film deposition, supporting consistent stoichiometry and electrical properties in NiO layers.
- Pellets form with 325 mesh for source loading: Supplied as pellets with 325 mesh particle size, this form factor facilitates uniform loading into e-beam hearths or boats and reduces spitting during evaporation.
Trade-offs
- Requires specific evaporation hardware: E-beam evaporation with graphite, Al2O3, or BN liner is preferred; thermal evaporation requires RFQ and may not be compatible with standard boats due to high melting point (1984°C).
- High melting point demands process control: With a melting point of 1984°C and density of 6.67 g/cm³, careful power ramping and source geometry are needed to avoid thermal shock or incomplete evaporation.
