This strontium titanate powder is intended for vacuum thin-film deposition and requires careful matching to deposition source hardware and process parameters. The Z-ratio of 0.31 and 90 nm particle size directly influence deposition rate accuracy and source loading behavior.
- Deposition Source Compatibility: Use E-beam evaporation with a hearth lined with graphite, Al2O3, or BN, or use thermal evaporation with a W, Mo, or Ta boat after RFQ approval.
- Process Route Matching: Select evaporation method based on material melting point and film requirements, with thermal evaporation requiring prior RFQ.
- Z-Ratio Application: Enter the Z-ratio of 0.31 into the deposition controller to ensure accurate thickness monitoring during evaporation.
- Particle Size Constraint: The 90 nm particle size must be verified for compatibility with source loading procedures and evaporation hardware.
- Pre-Order Validation: Confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before finalizing the order.
Why is a 90 nm particle size specified for SrTiO3 evaporation powder, and how does it impact film uniformity and deposition rate control?
The 90 nm particle size ensures consistent powder loading and controlled evaporation behavior in e-beam hearths. Finer particles provide high surface area and uniform thermal coupling, which improves deposition rate stability and film thickness uniformity. The specified Z-ratio of 0.31 further aids accurate rate monitoring with quartz crystal microbalances.
What evaporation source configurations are compatible with this SrTiO3 powder, and why is e-beam preferred over thermal evaporation?
The SrTiO3 powder is compatible with e-beam hearths using graphite, Al2O3, or BN liners, or with W/Mo/Ta boats for thermal evaporation. E-beam evaporation is preferred because SrTiO3 has a high melting point requiring direct energy input, and the 90 nm powder size enables efficient energy absorption; thermal evaporation is available by RFQ but may demand higher temperatures and careful liner selection to avoid contamination.
What storage and handling precautions are required for SrTiO3 nanopowder to maintain purity and prevent moisture absorption?
SrTiO3 nanopowder (90 nm) should be stored in a dry, inert atmosphere to prevent moisture absorption and particle agglomeration. The 99.9% purity specification demands careful handling to avoid contamination from airborne particles or ambient humidity; use a glovebox or vacuum desiccator for long-term storage and seal containers immediately after each use.
Strontium Titanate (SrTiO3) Evaporation Material, Powder, 99.9%, 90 nm is a research-grade compound evaporation material for vacuum thin-film deposition, supplied as a 90 nm powder with 99.9% purity and available in pack sizes from 25g to 1kg, optimized for E-beam evaporation with specific hearth liner or boat compatibility.
Positive
- Defined 90 nm particle size: The specified 90 nm powder form supports consistent source loading and controlled evaporation behavior, reducing variability in thin-film deposition runs.
- High purity 99.9% specification: The 99.9% purity level enables reliable comparison with standard and high-purity grades, facilitating process matching for demanding optical or electronic film applications.
Trade-offs
- E-beam evaporation preferred: Thermal evaporation requires RFQ and specific boat materials (W/Mo/Ta or graphite/Al2O3/BN liner), limiting direct drop-in use for thermal-only systems without prior compatibility confirmation.
- Z-Ratio of 0.31 requires calibration: The low Z-Ratio of 0.31 necessitates accurate quartz crystal microbalance (QCM) calibration for film thickness monitoring, adding a process setup step for precise deposition control.
