This material requires e-beam evaporation with a water-cooled copper hearth and a compatible liner of graphite, Al2O3, BN, or Ta. The high melting point of 1890°C and Z-ratio of 0.53 necessitate precise process control for consistent thin-film deposition.
- Deposition Method: Use e-beam evaporation as the preferred method; alternative methods may not achieve the required film quality.
- Source Liner Compatibility: Select a liner from graphite, Al2O3, BN, or Ta to match the evaporation source and material behavior.
- Thermal Management: Accommodate the melting point of 1890°C to prevent overheating or incomplete evaporation.
- Thickness Monitoring: Enter the Z-ratio of 0.53 into the quartz crystal monitor to ensure accurate film thickness measurement.
- Purity Verification: Confirm the 99.5% purity grade meets the film purity requirements for the intended application.
What is the significance of the Z-ratio of 0.53 for vanadium evaporation pellets in e-beam deposition?
The Z-ratio of 0.53 is a material-specific parameter used for quartz crystal microbalance (QCM) thickness monitoring. It corrects for the acoustic impedance mismatch between the deposited vanadium film and the quartz crystal, ensuring accurate deposition rate and film thickness control. This value is explicitly listed in the product specifications to support precise process calibration.
Which liner materials are compatible with vanadium evaporation pellets in an e-beam system?
The compatible liner materials include graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum). The product specifies a water-cooled copper e-beam hearth with one of these liners as preferred for evaporation. The choice depends on the high melting point of vanadium (1,890 °C) and chemical compatibility to avoid contamination or reaction.
How does the pellet size of 3–6 mm affect loading and evaporation performance in a vacuum deposition system?
The 3–6 mm pellet size is specified to support consistent source loading and uniform evaporation. This size range is compatible with standard e-beam crucible dimensions, allowing for efficient heat transfer and steady vapor flux while avoiding handling issues associated with fine powders. The product explicitly states that this sizing is chosen to support source loading and evaporation review.
Vanadium (V) evaporation pellets at 99.5% purity and 3-6 mm size are specified for e-beam deposition with defined thermal and density parameters, but require careful matching of evaporation source hardware and liner materials due to the high melting point of 1,890°C.
Positive
- 99.5% purity vanadium pellets: Vanadium evaporation material supplied as 3-6 mm pellets with 99.5% purity, suitable for research-grade thin-film deposition requiring defined material identity.
- Compatible e-beam evaporation parameters: Melting point (1,890°C), density (5.96 g/cm³), and Z-ratio (0.53) are specified to enable source loading and process optimization for e-beam evaporation with water-cooled copper hearth and compatible liners.
Trade-offs
- Requires source hardware matching: Evaporation source hardware and liner material (graphite, Al2O3, BN, Ta) must be selected based on vanadium's melting point and film requirements to avoid contamination or process failure.
- High melting point operational constraint: With a melting point of 1,890°C, the material demands a high-power e-beam system and careful thermal management, increasing infrastructure requirements for standard laboratories.
