This material requires thermal evaporation under vacuum using tungsten, molybdenum, or tantalum sources. Process parameters must account for the melting point of 1,453°C and apply a Z-Ratio of 0.331 for accurate film thickness monitoring.
- Source Compatibility: Use only tungsten, molybdenum, or tantalum evaporation sources to avoid contamination.
- Vacuum Requirement: Process in high vacuum to ensure clean film deposition.
- Temperature Control: Heat the source to the melting point of nickel (1,453°C) for evaporation.
- Thickness Monitoring: Apply the Z-Ratio of 0.331 when using a quartz crystal microbalance for film thickness monitoring.
How does the specified purity of 99.999% affect thin-film quality compared to lower-purity nickel evaporation materials?
The listed purity of 99.999% minimizes contamination in deposited films critical for applications requiring high electrical conductivity and low defect density in semiconductor or magnetic multilayer stacks. This specification allows direct comparison between standard-purity grades (e.g., 99.9%) and high-purity grades during process qualification without additional RFQ steps.
What evaporation source configurations are compatible with this nickel wire of diameter 2.0 mm?
This nickel wire is designed for thermal/resistive evaporation using tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats as stated in the specifications. The wire diameter of 2.0 mm must be confirmed against the deposition source geometry to ensure proper loading and consistent feed rate during vacuum thin-film deposition.
Why is the Z-Ratio of 0.331 important when using this nickel wire in quartz crystal microbalance thickness monitoring?
The Z-Ratio of 0.331 corrects the acoustic impedance mismatch between nickel and quartz crystal sensors during evaporation monitoring as provided in the technical specifications. Using an incorrect Z-Ratio leads to systematic film thickness errors; this value must be entered into the deposition controller for accurate in-situ measurement of nickel film thickness.
Atomfair's 99.999% pure nickel wire (2.0 mm diameter) is a research-grade thermal evaporation material designed for use with W/Mo/Ta sources, requiring pre-purchase verification of source geometry and process compatibility.
Positive
- Ultra-high 99.999% purity level: The 5N purity grade minimizes impurity incorporation in deposited thin films, which is critical for applications in electronics, catalysis, and magnetic multilayer structures where trace contamination degrades performance.
- Specified wire geometry for consistent loading: The 2.0 mm diameter wire form is specifically dimensioned to enable repeatable loading into thermal evaporation sources such as tungsten, molybdenum, or tantalum filaments, baskets, coils, or boats, reducing process variability.
Trade-offs
- Mandatory pre-purchase compatibility verification: Buyers must independently confirm that the 2.0 mm wire diameter, wire form, and purity grade match their specific evaporation source geometry and process requirements before ordering, as the product is not universally compatible without prior assessment.
- Fixed wire diameter limits source adaptability: The wire diameter is fixed at 2.0 mm; laboratories requiring different wire diameters, rod, or pellet forms must source alternative configurations, as this product cannot be modified.
