Niobium evaporation wire requires compatibility with water-cooled e-beam hearth or tungsten/tantalum support. Thermal evaporation is restricted to thin charge or qualified setups only.
- Evaporation Source Compatibility: Must use water-cooled e-beam hearth or tungsten/tantalum support by RFQ.
- Evaporation Method Restriction: E-beam evaporation is preferred; thermal evaporation is only acceptable for thin charge or qualified setups.
- Melting Point Constraint: High melting point of 2,468 °C necessitates high-temperature evaporation source and careful process control.
- Z-Ratio Process Requirement: Z-ratio of 0.492 must be accounted for in deposition rate monitoring to ensure accurate film thickness.
- Purity and Film Consistency: 99.99% purity ensures consistent film properties and minimizes contamination in thin-film deposition.
Why is e-beam evaporation preferred over thermal evaporation for the AF-NBWIR-4N2P0MM Niobium wire?
E-beam evaporation is preferred because niobium has a high melting point of 2,468°C and requires controlled energy delivery for stable deposition. Thermal evaporation is only suitable for thin charges or qualified setups, as stated in the product specifications: 'E-beam evaporation preferred; thermal only for thin charge/qualified setup.'
What deposition source hardware is compatible with the AF-NBWIR-4N2P0MM Niobium wire?
The specified evaporation source for this 99.99% pure niobium wire is a water-cooled e-beam hearth or tungsten/tantalum support by RFQ. This compatibility ensures proper thermal management and material handling during evaporation, as detailed in the technical specifications table.
What is the Z-ratio of this Niobium evaporation material and why is it important for deposition rate monitoring?
The Z-ratio is 0.492, as listed in the technical specifications. This value is critical for accurate film thickness control when using quartz crystal microbalance (QCM) monitoring in e-beam evaporation, as it corrects for the acoustic impedance mismatch between the deposited material and the quartz crystal sensor.
Niobium (Nb) evaporation wire (99.99%, 2.0 mm dia.) is supplied in wire form for e-beam evaporation, with high purity and defined dimensions; however, thermal evaporation is restricted to thin charge or qualified setups, and source compatibility must be confirmed.
Positive
- High purity 99.99% Niobium wire: Niobium wire at 99.99% purity minimizes contamination in thin-film deposition, ensuring consistent film properties for research-grade applications.
- Defined wire diameter 2.0 mm: The 2.0 mm wire form facilitates precise loading into e-beam hearths and supports reproducible evaporation rates.
Trade-offs
- Thermal evaporation restricted: Thermal evaporation is only recommended for thin charge or qualified setups; standard thermal evaporation may not be suitable without prior compatibility testing.
- Source hardware compatibility required: This material is designed for water-cooled e-beam hearths or requires custom tungsten/tantalum support via RFQ, adding lead time and procurement steps.
