This powder requires E-beam evaporation with a compatible liner; thermal evaporation is only feasible by RFQ. The material's high melting point (2,573°C) and defined Z-Ratio (1.00) necessitate precise deposition parameter matching and hardware compatibility checks.
- Evaporation Method Compatibility: This material is designed for E-beam evaporation using a compatible liner; thermal evaporation is only possible via RFQ due to high melting point and material behavior.
- Crucible Requirements: High-temperature crucible is required for this material, available by RFQ, to withstand the 2,573°C melting point.
- Particle Size Implication: The 450 nm powder particle size influences source loading density and evaporation rate uniformity during deposition.
- Z-Ratio Calibration: The Z-Ratio of 1.00 simplifies thickness monitoring but requires confirmation of quartz crystal sensor calibration for accurate deposition rate control.
What is the significance of the Z-ratio value of 1.00 for NbN evaporation material in thin-film deposition?
The Z-ratio of 1.00 for NbN is critical for accurate quartz crystal microbalance (QCM) monitoring during e-beam evaporation. It indicates that the material's acoustic impedance closely matches that of the quartz crystal, reducing the need for correction factors in thickness measurement. This value, explicitly listed in the technical specifications, ensures reliable real-time film thickness control when using QCM sensors.
Why is e-beam evaporation preferred over thermal evaporation for NbN powder, and what conditions are required for thermal feasibility?
E-beam evaporation is preferred for NbN powder due to its high melting point of 2,573°C, which requires the concentrated energy of an electron beam to achieve vaporization. The product description states that e-beam evaporation is preferred and that thermal feasibility is available only by RFQ, typically requiring a high-temperature crucible. This constraint is essential for researchers to consider when matching deposition hardware to the material's thermal behavior.
How does the density of 8.4 g/cm³ for NbN powder affect e-beam hearth loading and material consumption planning?
The density of 8.4 g/cm³, as given in the technical specifications, allows researchers to calculate the volume occupied by a given mass of NbN powder, which is critical for e-beam hearth loading. For example, a 25 g pack occupies approximately 2.98 cm³, guiding source capacity and deposition material budgeting. This parameter directly supports accurate process planning without relying on external material databases.
Niobium Nitride (NbN) evaporation powder at 99.9% purity and 450 nm particle size is evaluated for E-beam evaporation deposition of superconducting or hard-coating thin films, with a high melting point of 2,573°C and density of 8.4 g/cm³ requiring compatible hearth liners and high-temperature crucibles by RFQ.
Positive
- High-purity NbN for superconducting films: 99.9% purity and defined NbN stoichiometry support reproducible deposition of superconducting or wear-resistant nitride coatings with controlled composition.
- Specified 450 nm powder size: Powder 450 nm particle size facilitates consistent source loading and controlled evaporation rate in E-beam systems, reducing spitting or non-uniform flux.
Trade-offs
- High melting point requires specialized hardware: Melting point of 2,573°C necessitates E-beam evaporation with compatible hearth liners and high-temperature crucibles by RFQ, limiting thermal evaporation feasibility without custom setup.
- Density and Z-ratio affect process tuning: Density of 8.4 g/cm³ and Z-ratio of 1.00 require careful calibration of deposition rate monitors and source power to achieve target film thickness and stoichiometry.
