This nickel oxide evaporation material requires high-temperature evaporation using E-beam or thermal sources with specific liner or boat materials to avoid contamination and ensure film quality. The pellet form and 2mm size range must be verified against source geometry for proper loading and uniform evaporation.
- Evaporation Source Hardware Compatibility: The material requires either an E-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat for thermal evaporation.
- High-Temperature Processing Requirement: With a melting point of 1984°C, the evaporation source must be capable of reaching and maintaining this temperature under vacuum.
- Material Form and Size Compatibility: The pellet form and 2mm size range must be verified against the source geometry to ensure proper loading and uniform evaporation.
- Process Route Selection: E-beam evaporation is the preferred method, while thermal evaporation is available by request for quotation and requires specific boat materials.
- Z-Ratio for Deposition Monitoring: The Z-ratio of 1.00 is used for quartz crystal microbalance calibration to control film thickness during deposition.
What is the significance of the 99.5% purity grade for NiO evaporation pellets in thin-film deposition?
The 99.5% purity defines a standard research grade, balancing cost and film quality for general vacuum deposition. The product description explicitly states this purity enables comparison between standard, high-purity, and RFQ-controlled grades. For applications requiring higher purity, an RFQ submission is necessary.
Which evaporation source hardware is compatible with these NiO pellets?
These NiO pellets are designed for E-beam evaporation using a hearth with graphite, Al2O3, or BN liner, or alternatively with W/Mo/Ta boat. Thermal evaporation is possible only by RFQ. The melting point of 1,984°C and density of 6.67 g/cm³ are critical for matching source loading and power requirements.
How does the Z-ratio of 1.00 affect deposition process monitoring for these NiO pellets?
A Z-ratio of 1.00 simplifies quartz crystal microbalance (QCM) thickness monitoring because it is the standard calibration factor, eliminating the need for a correction factor. This ensures straightforward and consistent film thickness control during deposition, as stated in the technical specifications.
Atomfair's NiO evaporation pellets (99.5% purity, 2mm form) are optimized for E-beam evaporation with high-temperature hearth liners, but thermal evaporation requires RFQ; the high melting point demands robust source infrastructure.
Positive
- High Purity 99.5% NiO Pellets: The 99.5% purity specification enables consistent thin-film stoichiometry and reduces the risk of contamination in vacuum deposition processes.
- Optimized Pellet Form for E-Beam: The 2mm pellet size facilitates controlled source loading and stable evaporation rates in E-beam hearths with graphite, Al2O3, or BN liners.
Trade-offs
- Thermal Evaporation Requires RFQ: Thermal evaporation is not a standard option; it must be requested via RFQ, and the user must provide a compatible boat or liner material (W/Mo/Ta).
- High Melting Point Infrastructure Need: With a melting point of 1,984°C, the material requires high-temperature evaporation sources and appropriate thermal management, limiting compatibility with lower-temperature systems.
