Strontium Titanate SrTiO3 Powder 99.97% 90 nm ATOMFAIR®

This powder requires compatible hearth liner materials to prevent chemical reaction or contamination during evaporation. The Z-ratio value of 0.31 must be used for accurate quartz crystal microbalance calibration in thin-film deposition.

• Liner Compatibility: Select a hearth liner of graphite, Al2O3, BN, or a boat of W, Mo, or Ta to avoid chemical interaction with SrTiO3 at evaporation temperatures.
• Z-Ratio Calibration: Input the Z-ratio of 0.31 into the deposition controller to ensure correct film thickness measurement.
• Particle Size Consideration: The 90 nm powder particle size influences packing density and may require gentle handling to avoid segregation.
• Deposition Method Preference: E-beam evaporation is preferred for this material; thermal evaporation requires a formal request for quotation.
• Pre-Order Confirmation: Confirm deposition source geometry, quantity, and certificate requirements before placing an order.

This procedure outlines the preparation and loading of SrTiO3 powder for vacuum thin-film deposition. Adherence to the specified liner material and Z-ratio settings is critical for consistent film quality.

Required Equipment: E-beam evaporator, Hearth liner (graphite, Al2O3, BN, or W/Mo/Ta boat), Quartz crystal microbalance

1. Select Liner
   Select a compatible hearth liner or boat material based on the preferred evaporation method (E-beam or thermal).
2. Load Powder
   Load the SrTiO3 powder into the selected liner or boat, ensuring even distribution for consistent evaporation.
3. Calibrate Monitor
   Set the quartz crystal microbalance to a Z-ratio of 0.31 for accurate thickness monitoring during deposition.
4. Evacuate Chamber
   Evacuate the deposition chamber to the required vacuum level for the selected evaporation method.

Strontium Titanate (SrTiO3) Evaporation Material, Powder, 99.97%, 90 nm is a high-purity compound evaporation material for vacuum thin-film deposition, supplied as a 90 nm powder with a Z-ratio of 0.31, optimized for E-beam evaporation with specific hearth liners or boats, and available in pack sizes from 25g to 1kg.

Positive

• High purity for film quality: The 99.97% purity specification supports consistent stoichiometry and reduced contamination in deposited thin films, critical for electronic and optical applications.
• Defined particle size for evaporation: The 90 nm powder form facilitates uniform source loading and controlled evaporation rates in E-beam systems, improving process reproducibility.

Trade-offs

• E-beam evaporation preferred: Thermal evaporation requires RFQ and specific liner or boat materials (graphite, Al2O3, BN, W, Mo, Ta), limiting direct compatibility with standard thermal sources without prior hardware confirmation.
• Z-ratio requires calibration: The Z-ratio of 0.31 necessitates sensor calibration in quartz crystal monitors for accurate thickness control, adding setup complexity for operators unfamiliar with this parameter.
